Question

An angle measures 136° less than the measure of its supplementary angle. What is the measure of each angle?

Answer 1

22°, 158°

Explanation:

Let the angles be x and x-136

x + x - 136 = 180

2x = 316

x = 158

x - 136 = 22

Answer 2

158,22

Explanation:

Supplementary angles add to 180 degrees

x is the first angle

x-136 is the second angle

x+x-136 = 180

Combine like terms

2x-136 = 180

Add 136 to each side

2x-136+136 =180+136

2x =316

Divide each side by2

2x/2 =316/2

x=158

The second angle is

158-136 =22
