Let us begin by redrawing the quadrilaterals so that the congruent sides and angles become more obvious in the attachment:
From the diagrams, we have the congruent angles to be:
∠F, ∠K, ∠S
∠ I, ∠L, ∠T
∠G, ∠N, ∠R
∠H, ∠M, ∠Q
We can conclude that the correct option is:
∠M and ∠Q
13. Complete the paragraph proof.
Given: 21 and 22 are supplementary, and 22 and 23 are supplementary.
Prove: 21223
By definition of supplementary angles, m_1 = m22 = (a) and m22 - mz3 = (6)
Then, m_1 - m42 = m_2 + m23 by the
(c). Subtract mZ2 from each side. You
get m2l= (d), or 21 (e)
The complete paragraph proof is explained below.
What are supplementary angles?Two or more given angles are said to be supplementary when on adding there individual measure, it produce the sum of angles on a straight line i.e. 180^o.
To complete the paragraph proof, we have;
m<1 + m< = 180^o (definition of supplementary angles)
m<2 - m<3 = m<2 - m<1
m<1 + m<2 = m<2 + m<3 (by the addition property of supplementary angles)
subtract m<2 from each side,
m<1 + m<2 - m<2 = m<2 + m<3 - m<2
you will get;
m<1 = m<3
Therefore, m<1 ≅ m<3

What are the slope and y-intercept of the linear function shown in the grid?
Answer:
C Slope = -4/3, Y-Intercept = 4
Step-by-step explanation:
The Y- Intercept is where the line contacts the Y-Axis (the vertical line)
Since the line is going down, the slope is going to be negative. You fine the slope by finding a point the line goes through perfectly and then since its negative, go down however many it is until the line goes through another point perfectly, then go right and how many points it takes to get to the point is your denominator. (so your slope is -4/3)

The function f(x) represents the time it takes an airplane to travel east. The function g(x) represents the time it takes an airplane to travel west. Given f(x) = 4x 13 and g(x) = 10x − 2, solve for (f g)(x) to determine the total roundtrip time. (f g)(x) = 14x 15 (f g)(x) = 14x 11 (f g)(x) = 6x 11 (f g)(x) = 6x 15.
The total time taken for round trip will be (f+g)(x) = 14x+11
We have given that
f(x)=4x+13and g(x)=10x-2
What is the round trip time?In order to find the round-trip time, we have to add both functions to represent the time taken to travel east and the time taken to travel to west.
Therefore we get,
[tex](f+g)(x)=f(x)+g(x)\\ =(4x+13)(10x-3)\\ =4x+13+10x-2\\ =4x+10x+13-2\\ =14x+11[/tex]
Hence,The total time taken for round trip will be: (f+g)(x) = 14x+11

An individual head of a sprinkler system covers a circular area of grass with a radius of 25 feet. The yard has 3 sprinkler heads that each cover a circular area with no overlap. What is the approximate total area that will be watered? 1963. 5 ft 1963. 5 ft² 5890. 5 ft 5890. 5 ft².
The total area covered by the yard by the 3 sprinkler heads such that each covers a circular area with no overlap is 5892.857 ft².
What is the area of a circle?The area of a circle is the area covered by the circle with radius r. It is given by the formula,
[tex]\text{Area of circle} = \pi r^2[/tex]
As it is given that the area covered by a single sprinkler system is of the radius of 25 feet, therefore, the area covered by a singular sprinkler system can be written as,
Area of sprinkler = Area of a circle with radius 25 feet
[tex]\begin{aligned}\text{Area of sprinkler}&= \pi r^2\\&=\pi (25^2)\\&= 1964.2857 \approx 1964.286\rm\ ft^2\end{aligned}[/tex]
Now, as we know that the yard has three such sprinkler systems, therefore, the area covered by the sprinkler will be thrice the area covered by a single sprinkler,
The total area covered by the sprinkler = 3 x Area of sprinkler
= 3 x 1964.286
= 5892.857
Thus, the total area covered by the yard by the 3 sprinkler heads such that each covers a circular area with no overlap is 5892.857 ft².

Alfie has two sticks he puts the end to end in total it equals 80cm one stick is 10cm longer than the other stick how long is the longest stick
Solving
Alright so we know there are two sticks and that one is 10cm longer than the other. Knowing this information we can start off by dividing the total to make the sticks equal in length.
80cm ÷ 2 = 40cm
^ So currently each stick is 40cm
From here we have to make one stick 10cm longer so we would subtract 10cm from one and add that 10cm to the other one.
Stick 1: 40cm - 10cm = 30cm
Stick 2: 40cm + 10cm = 50cm
Answer
This means that the longest stick is 50cm in length
The length of the longest stick is 45cm.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
Let's call the length of the shorter stick "x".
According to the problem, the longer stick is 10cm longer than the shorter stick, so its length is x + 10.
Now we know that when the two sticks are put end to end, the total length is 80cm.
Therefore, we can write the equation:
x + (x + 10) = 80
Simplifying the equation, we get:
2x + 10 = 80
Subtracting 10 from both sides:
2x = 70
Dividing both sides by 2:
x = 35
The length of the shorter stick is 35cm, and the length of the longer stick is:
x + 10 = 35 + 10 = 45
Therefore,
The length of the longest stick is 45cm.

how do you find the measure of angle b with only angle c and the outside of angle a
Step-by-step explanation:
straight angle a + 117 = 180
a = 180 - 117
= 63
total angle in triangle = 180
63 + b + 81 = 180
b = 180 - 63 - 81
= 36
Answer:
b = 36°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
117° is an exterior angle of the triangle , then
b + 81° = 117° ( subtract 81° from both sides )
b = 36°
