Shyam is 0.9 m
Step-by-step explanation:
10 cm = 10/100 m = 0.1 m
Now,
Ram = 1m + 0.1 m = 1.1 m
Now,
shyam = 1.1 m - 20 cm
= 1.1 m - 20/100 m
= 1.1 m - 0.2 m
= 0.9 m
Triangle DEF is shown below. Which of the following equations could be used to find the value of x?
The equation that can be used to find x in the triangle is x + 86 = 180
How to find the angle of a triangle?A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.
Therefore, let's find the angle of x in the triangle.
Triangle DEF is shown above. Therefore, the equation that can be used to find the value of x can be calculated as follows:
49 + 37 + x = 180
Therefore, the equation is as follows:
x + 86 = 180

An equation that could be used to find the value of x is: B. x + 86° = 180°.
What are the properties of similar triangles?In Mathematics and Geometry, two (2) triangles are said to be similar when the ratio of their corresponding side lengths are equal and their corresponding angles are congruent.
Additionally, the sum of all of the interior angles of a triangle is always equal to 180 degrees. In this scenario, we can logically deduce that the sum of the given angles are supplementary angles:
m∠1 + m∠2 + m∠3 = 180°
37° + 49° + m∠3 = 180°
86° + m∠3 = 180°
x + 86° = 180° (required equation)

Which circle has the longest circumference? Why?
Answer: The longest part of the circle is called diameter. Diameter is a chord. It is equal to double of radius.
A chord is a line segment with both endpoints on the circle. The diameter is a special chord that passes through the center of the circle. The diameter would be the longest chord in the circle.

x^2 - y^2 = 100
x + y = 5
The solution to the given system of equations is
(x, y). What is the value of x - y?
Answer:
20
Step-by-step explanation:
Let's start by rewriting the second equation in terms of "x":
[tex]x+y=5[/tex]
Subtract y from both sides:
[tex]x=5-y[/tex]
Now, substitute "5-y" for "x" in the first equation:
[tex](5-y)^2-y^2=100[/tex]
Note that:
[tex](a-b)^2=a^2-2ab+b^2[/tex]
[tex]25-10y+y^2-y^2=100[/tex]
Cancel out like terms:
[tex]25-10y=100[/tex]
Subtract 25 from both sides:
[tex]-10y=75[/tex]
Divide both sides by -10
[tex]y=\frac{75}{-10}=\frac{15}{-2}=-\frac{15}{2}[/tex]
Now, substitute this value back into either of the equations to solve for x.
[tex]x+y=5\\x-\frac{15}{2}=5\\[/tex]
Add 15/2 to both sides:
[tex]x=5+\frac{15}{2}\\x=\frac{10}{2}+\frac{15}{2}\\x=\frac{25}{2}[/tex]
Now, find the difference:
[tex]x-y=\frac{25}{2}-(-\frac{15}{2})=\frac{25}{2}+\frac{15}{2}=\frac{40}{2}=20[/tex]
The segments in each figure are tangent to the circle at the points shown. Find each length.
Answer:
Step-by-step explanation:
Tangents from a common point are equal.
In other words AC = AB
AC = 8x
AB = 2x^2
2x^2 = 8x Divide both sides by 2x
2x^2/2x = 8x / 2x Divide
x = 4
AC = 8x
AC = 8*4
AC = 32
AB = 2x^2
AB = 2 (4)^2
AB = 2*16
AB = 32

Fred purchased a jacket for $20 and 5 T-shirts. Each T-shirt cost the same amount. The total cost was $85. How much did each T-shirt cost?
Answer:
Each t-shirt cost 13 dollars.
Step-by-step explanation:
Since the jacket was 20 bucks, we can set that aside:
85-20=65
Now that we've set that aside, there are five t-shirts. If they all cost the same, that means we can divide!
65/5=13
How to check?
Use inverse operations: 13*5=65
Re-add the 20 bucks from the jacket, and the bill is complete again! Use inverse operations: 13*5=65
Each shirt costs $13.

Explanation:
To get to the desired conclusion, you will want to make use of CPCTC and the fact that triangle AXB is congruent to triangle CYD. In order to show those two right triangles are congruent, it is sufficient to claim congruence of their hypotenuses and one internal acute angle (HA congruence). The corresponding internal angles are alternate interior angles where a transversal (BD) crosses parallel lines (AB║CD). It's tedious, but not terribly difficult.

Statement . . . . Reason
1. Congruent segment pairs are (AB, CD), (AD, BC) . . . . given
2. Perpendicular segment pairs are (AX, BD), (CY, BD) . . . . given

Additional comment
A lot of proof has to do with working backward, answering the question, "How do I know ...?" The beginning paragraph in this answer attempts to show you the answers to those questions.
This proof works with the smaller triangles AXB and CYD. You could do the same proof with the larger triangles AXD and CYB. For that, you'd have to claim that AD║BC.

What is the cost of 3 sweatshirts?
PLEASE SHOW HOW YOU GOT ITTT
I WILL MARK BRAINILIST
Answer:
$68.25
Step-by-step explanation:
1. First, to find the cost of one sweatshirt, we multiply 175 by 13, and then divide by 100.
[tex]175 * 13 = 2275[/tex] [tex]2275/100=22.75[/tex]2. Now, we know that one sweatshirt costs $22.75. To find the cost of three sweatshirts, we multiply 22.75 by 3.
[tex]22.75 * 3[/tex] [tex]68.25[/tex]Therefore, the cost of 3 sweatshirts is $68.25.

Remember that the sine is the ratio of the length of the opposite leg to the length of the hypotenuse.
Perhaps you know SOHCAHTOA, where SOH means sine, opposite, hypotenuse.
For angle J, leg LK is the opposite leg.
The hypotenuse of the triangle is the side opposite the right angle, teh angle of 90°, which is angle L, so the hypotenuse is side KJ.

Suppose that a and b are nonzero real numbers, and
that the equation x² + ax + b = 0 has solutions a
and b. Then the pair (a, b) is
The equation has two solutions. Means Discriminant means b^2-4ac >0
Here b = a.
a = 1
c = b
a^2 - 4b >0
a=2
b= -1
then a^2 - 4b > 0 = 4+4 > 0
therefore its 2, -1
The pair (a, b) represents the sum and product of the roots of the quadratic equation x² + ax + b = 0.
We have,
Given that the equation x² + ax + b = 0 has solutions a and b, the sum and product of the roots (a and b) can be related to the coefficients of the quadratic equation.
The sum of the roots of a quadratic equation is given by:
Sum of roots = -coefficient of x / coefficient of x² = -a
The product of the roots of a quadratic equation is given by:
Product of roots = constant term / coefficient of x² = b
From the given information, we have:
The sum of roots = a
Product of roots = b
Thus,
The pair (a, b) represents the sum and product of the roots of the quadratic equation x² + ax + b = 0.

Answer:
m∠C = 75°
Step-by-step explanation:
Theorem:
The consecutive angles of a parallelogram are supplementary (sum to 180°).
⇒ m∠D + m∠E = 180°
⇒ (7x + 21) + (15 + 5x) = 180
⇒ 7x + 21 + 15 + 5x = 180
⇒ 12x + 36 = 180
⇒ 12x = 144
⇒ x = 12
Theorem:
Opposite angles of a parallelogram are equal.
⇒ m∠C = m∠E
⇒ m∠C = 15 + 5x
Substituting found value of x:
⇒ m∠C = 15 + 5(12)
⇒ m∠C = 75°
Consecutive angles of a parallelogram are supplementary
