Question

Two angles are supplementary. The

larger angle is 18 less than 5 times
the smaller angle. How many
degrees is the smaller angle?

Answer 1

Explanation:

The sum of two supplementary angles is 180

Let A be the larger angle and B be the smaller angle

A+B=180

Given A=5B-18

5B-18+B=180

6B=180+18=198

B=198/6=33

A=180-B=180-33=147

Hence A=147, B=33
