There are several methods to find the measure of an unknown angle X in a triangle like angle sum property, Pythagorean theorem, trigonometric ratios, law of cosines and law of sines.

Using the Angle Sum Property: The sum of the measures of the angles in a triangle is always 180 degrees. If the measures of two angles in a triangle are known, then you can use the Angle Sum Property to find the measure of the third angle.

Using the Pythagorean Theorem: If a right triangle is given, we can use the Pythagorean theorem to find the measure of the right angle, which is 90 degrees.

Using the Sine, Cosine, and Tangent ratios: In a triangle, the measure of an angle can be found by using the ratios of the sides of the triangle. For example, the sine of an angle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.

Using the Law of Cosines or Law of Sines: The Law of Cosines and Law of Sines are two formulas that can be used to find the measure of an angle in a triangle if the measures of two angles and the lengths of two or three sides are known.

The fraction is Jayme thinking is 4/8

The term fraction is known as the expression that is used to represent the portion/part of the whole thing.

Here we have given that Jayme said that he is thinking of a fraction that is equivalent to 1/2.

Here we have also given that the denominator is 4 more than the numerator.

Let us consider that x be the value of the numerator.

Then the denominator is written as x + 4.

Here we have the equivalent fraction as 1/2.

Then it can be written as,

=> x/x+4 = 1/2

Cross multiply the terms, then we get,

=> 2x = x + 4

=> 2x - x = 4

=> x = 4

Then the denominator is calculated as,

=> x + 4 = 4 + 4 = 8

Answer:

Total Cost for Club Member = $15.00 + (n * $0.25)

Step-by-step explanation:

The equation for the total cost for a non-member to have n prints made is:

Total Cost for Non-Member = (n * $0.40)

This is because the club membership costs $15.00 initially, and each print for a club member costs $0.25 while each print for a non-member costs $0.40. So, the total cost is just the initial cost plus the cost of each print multiplied by the number of prints.

The money Glen must raise to reach his goal will be $440. And the minimum number of weeks it will take him to reach his goal will be 9 weeks.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Glen raised $275 for his softball team's fundraiser. He wants to raise at least $715. Let 'y' be the amount of money Glen must raise to reach his goal. Then the inequality is given as,

y + $275 ≥ $715

y ≥ $440

An expression or algebraic expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them.

Therefore, exponents are also called power or sometimes indices.

[tex]b^{p}[/tex] = {b × b × b × b × …. × b} p times

Squaring (or raising any other even power) is a non-invertible operation. Solving equations applying square roots involves squaring both sides of an equation.

For example to show the idea:

The equations: x−1 = 4 and x = 5, have exactly the same set of solutions. Namely: {5}.

Square both sides of x = 5 to get the new equation: x² = 25. The solution set for this new equation is; {−5,5}. −5 is an extraneous solution raised by squaring the two expressions

Square both sides of x−1 = 4 to get x² − 2x + 1 = 16

Vertical shift is the process of shifting a function up or down along the y-axis. Horizontal shift is the process of shifting a function left or right along the x-axis.

Vertical shift is a transformation of a graph which moves the graph up or down along the y-axis. This is done by adding or subtracting a constant value to the function’s output. For example, if the function is y = x, then by adding 2 to the right side of the equation, y = x + 2, the graph of the function will be shifted up 2 units. Similarly, if the function is y = x, then by subtracting 3 from the right side of the equation, y = x - 3, the graph of the function will be shifted down 3 units.

Horizontal shift is a transformation of a graph which moves the graph left or right along the x-axis. This is done by adding or subtracting a constant value to the function’s input. For example, if the function is y = x, then by adding 2 to the left side of the equation, y = x + 2, the graph of the function will be shifted right 2 units. Similarly, if the function is y = x, then by subtracting 3 from the left side of the equation, y = x - 3, the graph of the function will be shifted left 3 units.

By dividing the distance travelled by the time needed to cover that distance, uniform motion speed is found. Speed is calculated as follows:

  Speed = Distance / Time

    An object would move at a pace of 10 meters per second (100/10 = 10) if it covered 100 meters in 10 seconds.

  It is crucial to remember that the distance and time must both be expressed in the same unit in order to compute speed. For instance, the time must be expressed in seconds if the distance is expressed in meters.

 The motion in which an object moves in a straight line at a constant speed is often referred to as uniform motion. An object's speed is not constant and it is not thought to be moving uniformly if it is accelerating or decelerating.

 Therefore ,By dividing the distance travelled by the time it took to cover that distance, uniform motion speed is the rate at which an object moves in a straight line at a constant speed.

If Alang drove two hours in total at the same rate,( i.e., with 45 mph), he goes to ninty miles far away.

Distance is the measure of the space between two points or how far you travel. The rate is the measure of the speed that you travel and time is used to measure that how long you travel. When using the formula related to distance, rate, and time. If the rate in the problem gives miles per hour (mph), then time must be in hours. If time in minutes then divide the time by sixty. Distance in terms of rate is defined as the product of rate of object and time taken to cover the required distance. Use the formula:

Distance = rate × time

We have , distance drive by Alang in 30 minutes = 22.5 miles

So, rate/ speed with which Alang drives

= 22.5/30 /60 miles per hour

= 22.5 × 2 = 45 mph

Rate of driving = 45 mph

If he drove two hours in total at the same rate, we have to determine the distance travelled by him in these two hours. Time , t = 2 hours

Distance = 45 miles per hour × 2 hours
