Answer:
x = 41
Step-by-step explanation:
(2x+20) + (2x-4) = 180 degrees
4x+16 = 180 degrees
4x = 164
x = 41
The two sides are supplementary and add up to 180 degrees.

A) x/y = 2/3
B) x + y = 105
Solving Equation A for y
A) y = 1.5x
Substituting A into B
B) x + 1.5x = 105
2.5x = 105
x = 42
y = 63
Answer:
answer is B
