Question 211753: The measure of an angle is 9 more than twice the other angle. If the two angles are supplementary angles, find the measure of each angle.

You can put this solution on YOUR website! Let x = angle, y= supplement,,or y=180-x
.
y= 2x +9,,,,,,,given
.
180-x = 2x +9
.
-3x = - 171
.
x=57,,,,,,,,y=180-57 = 123
.
check, 57 +123=180,,,ok
.
123 = 2(57) +9 = 123,,,ok
