Question

An angle measures 160° less than the measure of its supplementary angle. What is the measure of each angle?

Answer 1

The two angles are 10 degrees and 170 degrees.

Explanation:

Supplementary angles add up to 180 degrees.

Let the angle be called "x", and the supplementary angle be called "180-x"

Converting words to math: x-160=180-x

Add x to both sides: 2x-160=180

Simplify: 2x=20

Divide by 2: x=10
