Angle A and Angle B are supplementary. The measure of angle B is 3 times the measure of angle A.

Find the measures of Angle A and Angle B.

If the angles are supplementary, then you know that they add up to 180 degrees.
A = 1 time A B = 3 times A
Total: (1 time A + 3 times A) = 4 times A
4 times A = 180 degrees
Divide each side by 4 :
1 time A = 180/4 = 45 degrees
A = 45 degrees
***B = ***3 times A = 135 degrees

The measures of Angle A and Angle B are 45 degrees and 135 degrees, respectively. Angle B is three times larger than Angle A, and together they sum up to 180 degrees.
