Question

An angle is double its complement. find the angle and the complement

Answer 1

Complement means the other angle that will sum up to 90°

So:

x + 2x = 90°
3x = 90
x = 30°

So, it is 30° and 30 * 2°, or 60°

Answer 2

60⁰

Explanation:

Angke = x

Complement = 90 - x

Given:

x = 2 (90 - x)

x = 180 - 2x

3x = 180

x = 60⁰

Complement = 30⁰
