Question

I don't know how to solve this:

In a pair of complementary angles, one angle measures 18* less than three times the other angle. Find the measure of each angle.

Answer 1

18, 72

Explanation:

Two angles are complementary if they sum up to 90°. Call them
`x, (90-x)`. From the second part,

`</p><p>3 x = 90-x+18 \\</p><p>4x = 72 \\</p><p>x= 18`

The second angle is
`90-18 = 72`
