Question

Sally drew a circle with right triangle PRQ inscribed in it, as shown below: The figure shows a circle with points P, Q, and R on it forming an inscribed triangle. Side PQ is a chord through the center, and angle R is a right angle. Arc QR measures 40 degrees. If the measure of arc QR is 40°, what is the measure of angle PQR?
20°
40°
50°
70°

Answer 1

Answer:

70*

Step-by-step explanation:

we have a right triangle - r is 90*

based on geometric rules: angle RPQ = 20       40 : 2

90 + 20 = 110

110 + x = 180

triangle have 180*

it means that 180 - 110 =

70 *
