Answer 7

If arc QR = 100, then arc PR is 80 because arc QRP is a semicircle.
A semicircle has measure 180

Answer 8

Angle PQR is an inscribed angle of a circle.

The measure of an inscribed angle is 1/2 of its intercepted arc.

The intercepted arc is arc PR.

Take half of its measure and that is the answer.

So, what is the answer?

One-half of 80 is not 50. Try again.
