If you go to a site called Desmos and type in all these choices you would get your answer a lot faster. But anyways, It would be C.
Hope this helps! :)
Answer:
What grid?
Step-by-step explanation:
Answer:
x = 107
Step-by-step explanation:
44+29+107=180
a triangle equals 180 with all the degrees added together :)
The part of the proof that uses the justification that angles with a combined degree of 90° are complementary is; Congruent Complements Theorem
<h3>How to prove complementary angles?</h3>
We are given;
m∠1 = 40°
m∠2 = 50°
∠2 is complementary to ∠3
We want to prove that ∠1 ≅ ∠3
Now, when the sum of two angles equals 90°, they are called complementary angles.
Now, looking at the angles, the proof that ∠1 ≅ ∠3 is Congruent Complements Theorem. This is because If two angles are complements of the same angle (or congruent angles), then the two angles are congruent.

Let width be x so
Length is equal to x+6
Perimeter= 2(l+b)
So perimeter=2(x+x+6)
P=2(2x+6)
4x+12=64 (given)
Send 12 to the other side then,
4x=64-12=52
X=52/4=13
