Since the two angles are supplementary, their measures add up to 180°. Therefore, we can set up the equation:
15 + X = 180
Subtracting 15 from both sides, we get:
X = 180 - 15
X = 165
Therefore, the measure of angle MCBD is 165°.
Use facts about supplementary angles to solve the following problem. Two angles are supplementary and have measures MA equals 15° and MCBD equals X degrees what is the value of MCBD
