Question

Look at triangle PQR with its incenter at O. What is the measure of angle PQR?

Answer 1

Options: 24 degrees

32 degrees

52 degrees

64 degrees

Answer 2

B/2+Q/2+128=180
20+Q/2+128=180
Q=64

Answer 3

the angles of triangle are bisected
so angle orq = 20 degrees
making angle oqr = 180 - (128+20) = 32 degrees
so angle pqr = 32*2 = 64 degrees

Answer 4

Thanks guys!
