Answer:
Total area = 51 in²
Step-by-step explanation:
Section the shape into a rectangle and a triangle.
Area of a rectangle = width x length
⇒ area = 6 x 7 = 42 in²
Area of a triangle = 1/2 x base x height
⇒ area = 1/2 x (6 - 3) x (13 - 7) = 9 in²
Total area of composite shape = 42 + 9 = 51 in²

Answer:
A, B, C, and E
Step-by-step explanation:
y = 4x - 20
8x - 2y = - 20 (divide everything by 2)
4x - y = -10
-y = -4x - 10
y = 4x - 10
4x - 10 = 4x - 20
0 
-10

Hi the answer is b=180-a-c
We have to subtract a from both sides
a+b+c+-a=180- a
b+c= 180 - a
Now subtract c from both sides
b+c-c = 180 - a - c
b=180 - a - c
