Question

PLEASE HELP ME QUICK!!

If angle A and angle B are supplementary angles and angle A is three times as large as angle B, find the measures of angle A and B

Answer 1

Supplementary= 180 degrees

It took me a minute- but all you needed to find was half of 180 then divide that by two to get the answer.

180/2= 90

90/2= 45

Angle A= 45(3)= 135

Angle B= 45

135+45= 180

Angle A= 135 Angle B= 45

I hope this helps!
