If anglea and angleb are supplementary angles, and anglea = 63°, find the measure of angleb. a. b = 27° b. b = 63° c. b = 117° d. b = 153°

C.   B=117°.

Step-by-step explanation:

We know that if a pair of angle are supplementary then their sum is added up to 180 degrees.

Given : angle A and angle B are supplementary angles.

i.e

Also, angle A = 63°

i.e  

i.e  

i.e  

Hence, the measure of angleB is 117°.
