Question

two angles are supplementary if the sum of their measures is 180 degrees. the measure of the first angle is 18 degrees less than two times the second angle. find the measure of each angle

Answer 1

66 and 114

Explanation:

y+x=180

y=2x-18

now substitute

2x-18+x=180

3x=198

x=66

now we can also solver for y

66+y=180

y=114
