Corresponding angles are congruent and appear on the same side of the transversal (the dividing line). Out of the answer choices, letter A (angles 1 and 5) fit that description. Hope this helped

Answer:
Trapezoid Median Theorem
Step-by-step explanation:
The Trapezoid Median Theorem says ...
The median of a trapezoid is parallel to each base and the length of the median equals one-half the sum of the lengths of the two bases.

That's the theorem that would seem to be applicable here.
Direct variation can be written as a proportion. Therefore, we can write:
Cross multiply to get:
4y=40
Divide by 4 on both sides to get that
y=10.
:)
4x - 3y = -11
-7x - 8y = 6
We need to cancel out one of the variables so let's multiply the first equation by 8 and the second by 3 and aim to cancel y.
32x - 24y = -88
-21x - 24y = 18
Now we subtract,
53x = -106
x = -2
3y = 4x + 11 = 4(-2) + 11 = 3
y = 1
Answer: (x,y)=(-2,1)
Check:
4(-2) -3(1) = -8 - 3 = -11, good
-7(-2) - 8(1) = 14 - 8 = 6, good
