Question

The supplement of an angle is four times as large as the complement of the same angle. What is the measure of the angle?

Answer 1

60°

Explanation:

Let the angle be x. Then, its supplement is (180°-x) and its complement is (90°-x).

`180-x=4(90-x) \\ \\ 180-x=360-4x \\ \\ 3x=180 \\ \\ x=60^(\circ)`
