Find the measures of two supplementary angles if one angle is 18 degrees more than twice the other.
.
Let x = measure of one of the angles
then from "18 degrees more than twice the other" we have
2x+18 = measure of second angle
.
Then, because they are "supplementary":
x + 2x+18 = 180
3x+18 = 180
3x = 162
x = 54 degrees
.
Second angle:
2x+18 = 2(54)+18 = 108+18 = 126 degrees
.
answer: 54 and 126 degrees
