Question

Triangle PQR and Triangle PSR are inscribed in circle A. What is mQPR?

Answer 1

you can label the "lengths" of the arcs... they are twice the "inscribed angle"

that means you know m arc RQP and the m arc QP
subtract to find the m arc RQ

finally, the inscribed angle QPR is ½ of the measure of arc RQ

Answer 2

What's the inscribed angle i use to find RQP

Answer 3

mQPR=42

Answer 4
