Sum of interior angles in Polygon:A polygon is a geometric object with two dimensions and a finite number of sides. A polygon's sides are made up of segments of straight lines that are joined end to end. As a result, a polygon's line segments are referred to as its sides or edges.
The geometric shape known as a pentagon has five sides and five angles. Penta here means five, and gon means angle. One of the different kinds of polygons is the pentagon. A regular pentagon's internal angles add up to 540°.
Here we have a five-sided Polygon
And the angles are 127°, 112°, 108°, 120°, and x°
As we know the sum of angles = 540°
=> 127° + 112° + 108° + 120° + x° = 540°
=> 467° + x° = 540°
=> x° = 540° - 467°
=> x° = 73°
Therefore,
The value of x is 73°

Answer:
(b) 14
Step-by-step explanation:
You want the difference of functions f(x) = 3x² +1 and g(x) = 1 -x when x=2.
DifferenceThe notation (f -g)(x) means f(x) -g(x). Then (f -g)(2) is ...
f(2) -g(2) = (3·2² +1) -(1 -2) = 13 -(-1) = 14
The value of (f -g)(2) is 14.
Graph the quadrilateral with the given vertices in the coordinate plane.
Because EF = GH = 4, EF≅GH, Because these are vertical line segments, their are slope undefined and they are parallel. EF and GH are opposite sides that are equal and parallel. So, EFGH is a parallelogram by the definition of a parallelogram.
What is a parallelogram?
A parallelogram is a simple quadrilateral with two pairs of parallel sides in Euclidean geometry. A parallelogram's opposite or facing sides are equal in length, and its opposite angles are equal in size.
Given that E(-3,0), F(-3,4), G(3,-1),H(3,-5)
The quadrilateral is attached below.
The distance between two points (x₁, y₁) and (x₂, y₂) is √[(x₂ - x₁)² + (y₂ - y₁)²].
The length of EF is √[(-3 -(-3))² + (4- 0)²] = √4² = 4
The length of GH is √[(3 -3)² + (-1- (-5))²] = √4² = 4
Therefore, EF = GH = 4
The line segments are congruent.
The line segments are vertical, thus the slope of the line is undefined.
If opposite sides are equal and parallel, then the quadrilateral is a parallelogram.

Winter has just begun. After one week, the temperature decreased by 46.8° with a
percent change of 72%. What was the temperature at the beginning of the week and
what is the temperature now?
The temperature at the beginning of the week was 166.43°, and the temperature now is 119.63°.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
Let's represent the initial temperature "T". Then, the temperature after one week is T - 46.8.
The percent change in the temperature is given as 72%. So, we have:
(T - 46.8) / T = 72% / 100%
Solving for T, we get:
T = 46.8 / (1 - 72%) = 46.8 / 0.28 = 166.43°
So the temperature at the beginning of the week was 166.43°, and the temperature now is 166.43° - 46.8° = 119.63°.

Sides of three square rooms measure 13 feet each, and sides of two square rooms measure 15 feet each. Which expression shows the total area of
these five rooms?
A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.
We know that a square has 4 sides of the same length, meaning that the length and the width are the same length. You can solve for the area of the first three rooms with a length of 13 feet using an equation like this:
(13 × 13) × 3
Now, for the other two rooms with the length of 15 feet:
(15 × 15) × 2
Simply add them together.
([13 × 13] × 3) + ([15 × 15] × 2)
Simplified, the expression would look like this:
(169 × 3) + (225 × 2) = 957
Therefore, the expression that shows the total area of these five rooms would look like this: ([13 × 13] × 3) + ([15 × 15] × 2), or it being simplified would look like this: (169 × 3) + (225 × 2) = 957

A transition known as a dilation enlarges or reduces an object by a certain amount. Using a scale factor of 2, we can dilate a triangle.
What exactly does it mean to "dilate" a triangle?I One way to make related figures is through dilation. By multiplying distances by the scale factor, each point is drawn farther away from the central point D. In the event when the scale factor is greater than 1, outward. The triangle's shape can be modified by moving the points A, B, and C.Assume that in the coordinate plane, the origin (0, 0) serves as the center of dilation. The original triangle's coordinates are multiplied by the scale factor (if it is 1/2) at each point if the scale factor. Multiply by half after a scale factor of 1/2 dilation. By multiplying the coordinates of each vertex by the scale factor, a triangle can be enlarged by a factor of 2/3. The new coordinates will be (2/3x, 2/3y), for instance, if the vertex's coordinates are (x, y).The complete question is,

Pyramid have faces=n triangles & 1 n-sided polygon
Edges=2n
vertices=n + 1
What are edges?An edge is a line segment that serves as a transition between two faces. It is also sometimes referred to as the line segment that connects two vertices.
What are vertices?The location where two or more edges intersect is the formal definition of the vertex in mathematics. The corner points are called vertices.
What are faces?A solid's face refers to each unique flat surface. Solids have multiple faces.
The number of faces in a pyramid is equal to one more than the base's polygon's number of sides.
faces = n triangles & 1 n-sided polygon
One more than the number of sides at the base of the polygon makes up the number of vertices in a pyramid.
hence, vertices = n + 1
Two times the number of sides at the base of a polygon equals the number of edges on a pyramid.
Therefore, edges = 2n

What do you mean by research paper?A research paper is a written work that presents the results of original research or provides an in-depth analysis of a particular topic or issue. Research papers are typically written by scholars, academics, or students, and are commonly submitted as part of a course assignment, a doctoral or master's degree requirement, or for publication in a scholarly journal.
A research paper typically includes several key elements: an introduction that provides background information on the topic and sets the stage for the rest of the paper; a literature review that summarizes existing research on the topic; the methodology section that describes the methods used to conduct the research; the results section that presents the findings of the research; and a discussion or conclusion section that interprets the results and places them in the context of the broader field of study.
The writing style of a research paper is usually formal and objective, with a focus on clearly and accurately communicating the results of the research. Research papers often include citations and references to other works, which demonstrate the writer's familiarity with the literature and support the validity of their findings.
If 1/6 of the people with AIDS are in their 20s, then 1/6 of 133,758 cases is 133,758 / 6 = 22,293 cases.

If f(x) = 8 – 10x and g(x) = 5x + 4, what is the value of (fg)(–2)?
Answer:
(fg)(-2) = 18
Step-by-step explanation:
f(x) = 8 – 10x
g(x) = 5x + 4
To find (fg)(-2) or f(g(-2)), first let's find g(-2) by subbing -2 in for x in g(x):
g(x) = 5x +4
g(-2) = 5(-1) +4 = -5+4 = -1
Knowing g(-2)=-1, we can now find f(g(-2)) by subbing -1 in for x in f(x):
f(x) = 8 – 10x
f(-1) = 8 - 10(-1) = 8+10 =18

The key features of the graph of the function would be
1) Domain - (1, infinity).
2) The range of the function is (2, infinity).
3) The graph of the function is a monotonically increasing function.
4) The graph of the function is asymptotic to the x-axis as it approaches x = 1.
5) The graph is a straight line, that is passing through the point (1,2) and has a slope of 1.
6) The graph is a shifted version of the function log2(x) by 2 units upward.
What is the graph of the function?
The graph of a function is a visual representation of the relationship between the inputs and outputs of the function. It is a diagram that shows the set of all possible points (x,y) that satisfy the equation of the function y = f(x) or in the case of a multivariable function y = f(x,z).
The graph of the function g(x) = log2(x-1) + 2 has several key features. Some of these features include:
1) The domain of the function is (1, infinity) since the logarithm is defined for x>0 and x-1 >0.
2) The range of the function is (2, infinity) since the minimum value of log2(x-1) + 2 is 2.
3) The graph of the function is a monotonically increasing function, meaning that as the input x gets larger, the output g(x) also increases.
4) The graph of the function is asymptotic to the x-axis as it approaches x = 1. This means that as x gets closer to 1, the graph of the function gets closer to the x-axis but never touches it.
5) The graph is a straight line, that is passing through the point (1,2) and has a slope of 1.
6) The graph is a shifted version of the function log2(x) by 2 units upward.
