Question

1. in the figure, (overrightarrow{cp}) and (overrightarrow{pb}) are perpendicular. what is the measure of (angle apc)? 90° 45° 135° 180°

Explanation:

Step1: Recall perpendicular - angle property

Perpendicular lines form right - angles.

Step2: Identify $\angle APC$

Since $\overrightarrow{CP}$ and $\overrightarrow{AP}$ are perpendicular at point $P$, the measure of $\angle APC = 90^{\circ}$.

Answer:

$90^{\circ}$
