Answer 2

Solution:


Two angles are called supplementary when their measures add up to 180 degrees.

Given:
Angle A = 2x + 32
Angle B = 2x + 20

(2x + 32) + (2x + 20) = 180

2x + 32 + 2x + 20 = 180

4x + 52 = 180

4x = 180 - 52

4x = 128

x = 32


Angle A = 2x + 32 = 2(32) + 32 = 96
Angle B = 2x + 20 = 2(32) + 20 = 84

Therefore, Angle A = 96 degrees

Hope this will help.
