Use facts about supplementary angles to solve the following problem. Two angles are supplementary and have measures mabc =15 and mabc =15 and mcbd=x what is the value of mcbd

15
165
180
75

Based on the given information, we know that angle ABC and angle CBD are supplementary angles. This means that their measures add up to 180 degrees.

We are given that the measure of angle ABC is 15 degrees: m(ABC) = 15.

To find the measure of angle CBD, we'll subtract the measure of angle ABC from 180 degrees:

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

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