Question

Find the measure of an angle such that the difference between the measures of its supplement and three times its complement is 60°

The measure of the angle is

Answer 1

X=50

Explanation:

x is the angle

180 - x is its suplement

90 - x is its complement

(180 - x) - 3(90 -x) = 10

180 - x -270 +3x = 10

-90 + 2x = 10

2x = 100

X = 50
