Question

Two angles are supplementary. The measure of one angle is eight times the measure of the other. Find the measure of each angle.

Answer 1

The small angle is 20

The large angel is 160

Explanation:

x + y = 180

x = 8y Substitute for x in the top equation

8y + y = 180 Combine

9y = 180 Divide by 9

y = 180/9

y = 20

x = 8y

x = 8 * 20

x = 160
