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

Since the two angles are supplementary, their measures add up to 180 degrees. Thus, we can set up the equation:
15° + x° = 180°
To solve for x, we subtract 15° from both sides:
x° = 180° - 15°
x° = 165°
Therefore, the value of m∠CBD is 165 degrees.
