Use facts about supplementary angles to solve the following problem. Two angles are supplementary and have measures m LABC = 15° and m LCBD = x°
What is the value of m. LC BD? (1 point)
Since LABC and LCBD are supplementary angles, their sum must equal 180 degrees.
So, m LABC + m LCBD = 180 degrees
Replacing the given values, we have:
15 + x = 180
Subtracting 15 from both sides, we get:
x = 180 - 15
x = 165
Therefore, the value of m LCBD is 165 degrees.
