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?

20 °

40 °

50 °

70 °

50degrees

Step-by-step explanation:

The sum of angle in the triangle is 180degrees, hence;

<PQR + arcQR + 90 = 180

<PQR + 40 + 90 =180

<PQR + 130 = 180

<PQR = 180 - 130

<PQR = 50degrees

Hence the measure of angle PQR is 50degrees
