Since the measure of angle ABC is 15° and the two angles are supplementary, the measure of angle CBD can be found by subtracting the measure of angle ABC from 180°.
m∠CBD = 180° - 15°
m∠CBD = 165°
Use facts about supplementary angles to solve the following problem. Two angles are supplementary and have measures m∠ABC=15° and m∠CBD=x°. What is the value of m∠CBD
?
