Question

D) 65 degrees

Answer 2

Answer 3

50

Remember in rotational motion the displacement can be measured in degrees or radians so we can say that if a body rotated from point R to Q it did a displacement of 50 degree
so the angle QPR = 50 degree

Other way measure of arc = central angle measure.

to get the arc length in rad = 50 *pi/180
