Question 381797: Two angles are supplementary. The larger angle is 12° more than twice the measure of the smaller angle. Find the measures of the two angles. (Supplementary angles are two angles whose sum is 180°.)
I'm supposed to solve this one by addition?

A%2BS=180
S=2A%2B12
Substitute,
A%2B2A%2B12=180
3A=168
A=56degrees
Then
56%2BS=180
S=124degrees
