Answer 1

A

Explanation:

Angle P is intercepted by two arcs.

SB and RQ.

We can use this theorem,

If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.

So in other words,

`(80 + 150)/(2) = rpq`

`rpq = 115`
