The correct answer is 165°.
Supplementary angles add up to 180°.
Given that m∠ABC = 15°, we can use this fact to determine the value of m∠CBD.
Since m∠ABC and m∠CBD are supplementary, their sum must be 180°.
So, if m∠ABC = 15°, then m∠CBD = 180° - 15° = 165°.
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
