To determine the measure of angle B, we need to use the fact that angles A and B are supplementary, which means they add up to 180°.
Since angle A is 117°, we can subtract this from 180° to find the measure of angle B:
180° - 117° = 63°
Therefore, the measure of angle B is 63° and angles A and B are supplementary.
B) 63° and supplementary
In the diagram below, if the measure of angle A is 117°, what is the measure of angle B? Are angles A and B complementary or supplementary?: *
A) 63° and complimentary
B) 63° and supplementary
C) 27° and complimentary
D) 27° and supplementary
