Question

The measure of an angle is eight times the measure of its supplementary angle. What is the measure of each angle?

Answer 1

160°

Explanation:

Let one angle be x

Let second angle be 8x

Sum of supplementary angles = 180°

x+ 8x = 180°

9x = 180

x = 180/9 = 20

First angle= x= 20°

Second angle = 8x = 8*20 = 160°
