use facts about supplementary angles to solve the following problem two angles are supplementary and have measure m abc = 15 and m cbd = x what is the value of m cbd

1 answer

Since the two angles are supplementary, their measures add up to 180 degrees.

Given that m(ABC) = 15, we can use the fact that the two angles are supplementary to find the measure of angle CBD:

m(ABC) + m(CBD) = 180
15 + x = 180
x = 180 - 15
x = 165

Therefore, the value of m(CBD) is 165 degrees.
