QuestionIdentify the mistake in concluding $m \angle P T R=50$ using angles $(x+28)$ and $(2x+16)$. Choose A, B, C, or D.

Studdy Solution
The student's mistake was using the definition of complementary angles instead of the definition of supplementary angles. Complementary angles add up to90 degrees, while supplementary angles add up to180 degrees. In this case, the angles PTQ and RTS are supplementary, not complementary.
Therefore, the correct answer is. The student used the definition of complementary angles instead of the definition of supplementary angles.
