Question

I say it's A.

Sally drew a circle with right triangle PRQ inscribed in it as shown below.



If the measure of arc QR is 40°, what is the measure of angle PQR?
Answer
20°
40°
50°
70°

Answer 1

It's 50° , the arc QR is nothing but the angle QPR and we already know that PRQ is 90° , so PQR is 180°-(90°+40°)=180°-130°=50° :D
