Respuesta :

I think the best answer to it is letter D. 90degrees because the P is the point of rotation by 90 degree so it means when C' is form the vertex is P and the angle that is formed by the 2 sides is 90. I hope you are satisfied with my answer and feel free to ask for more.

The correct answer is:

D. 90°

Explanation:

The measure of the angle from the pre-image point C to the image point C' through the center of rotation, P, will be the same as the angle of rotation.  Since the measure of the angle of rotation is 90°, then the measure of angle CPC' will also be 90°.
