Use facts about supplementary angles to solve the following problem. Two angles are supplementary and have measures m∠ABC = 15° and m∠CBD m∠CBD? (1 point) What is the value of
180°
15
165°
75
The two angles are supplementary, which means they add up to 180°.
Given that one angle has a measure of 15° (m∠ABC = 15°), we can subtract that from 180° to find the measure of the other angle:
180° - 15° = 165°
Therefore, the value of m∠CBD is 165°.
