Look at triangle PQR with its incenter at O. What is the measure of angle PQR?
Options: 24 degrees 32 degrees 52 degrees 64 degrees
B/2+Q/2+128=180 20+Q/2+128=180 Q=64
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
