Answer:

Angle A= 135 degrees and Angle B= 45 degrees

Step-by-step explanation:

Supplementary means two angles added together to make 180.

Angle A= 3x  and Angle B= x

So 3x +x =180

4x=180 divide both sides by 4

x =45

So Angle A = 3 times 45 =135 degrees

Angle B= the value of x which is 45 degrees
