Buy definition of Central angle. angle C A B = measure arc C A B equals to 60 degrees therefore measure arc CP B equals to 60 degrees. the measure of inscribed angle is always half of the measure of intercepted arc,hence measure angle cob=half ×60°=30°.By property of cyclic quadrilateral angle cob+angle cpb =180°. 30°+angle CPB=180°. angle CPB=180°-30°=150°

player1234: Buy definition of Central angle angle C A B = to measure Arc cpb angle C A B = 260 degree Hans at CP B equals to 60 degrees the measure of inscribed angle is half of the measure of intercepted Arc hence measure angle cob= half×60°= 30°.

player1234: By property of cyclic quadrilateral .

player1234: angle cob+angle cpb= 180°. 30°+ angle çpb = 180°, angle cpb =180°-30°=150°

player1234: yeh answer hai

vinita209: OK thnx
