Question

Which angle is supplementary to angle P? 25° P 155° 45° O 65° 90°

Answer 1

Two angles are supplementary when they add up to 180º.

Then, angle P and supplementary angle (x) must add 180:

`\begin{gathered} 25+x=180 \\ x=180-25 \\ x=155 \end{gathered}`Then, supplementary angle of angle P is 155º
