the measure of the supplement of an angle is 20 more than three times the measure of the original apple. find the messures of the angles.
.
Let x = original angle
then
3x+20 = supplement
.
x + (3x+20) = 180
4x+20 = 180
4x = 160
x = 40 degrees
.
supplement:
3x+20 = 3(40)+20 = 120+20 = 140 degrees
.
answer: 40 and 140 degrees
