Acircle is drawn with a right triangle prq inscribed in it. if the measure of arc qr is 40 degrees, what is the measure of angle pqr?

I believe the measure of angle PQR would be 50 degrees. The triangle is a right triangle, meaning one angle is 90 degrees.

1) 90 + 40 = 180
    90 + 40 = 130
2) 180 - 130 = 50
Therefore, Q is 50 degrees. The whole triangle is 180 degrees.

Just turn the whole gym into pie
