Question

Could someone help me.

Answer 1

Explanation:

The central angle of the two arcs (marked as 40 degrees each) means that <HPN = 80. The central angle = the arc measurement.

Now here's the tricky part. Any point on the circumference of a circle that has the same measurement using NH as a chord = 1/2 the central angle.

So <HRN = 1/2 the central angle

Since the central angle = 80, then 1/2 of it = 40

<HRP = 40 degrees because PR is a part of RN
