Question

Find the measure of an angle such that the difference between the measures of its supplement and four times its complement is 30

Answer 1

70 degrees

Explanation:

x = angle

180 - x = it's supplement

90 - x = it's compliment

(180 - x) - 4(90 - x) = 30

180 - x - 360 + 4x = 30

reducing

3x = 210

x = 70
