Question

In Fig. 10.88, APB is a tangent to a circle with centre O at point P. If ∠QPB = 500, then the measure of ∠POQ is
A. 100°
B. 120°
C. 140°
D. 150°

Answer 1

Answer:

100

Step-by-step explanation:

opb =90°

qpb=50°

opq+50°=90°

opq=40

anglep=angleq

40+40+angle o=180

angle o=180-80

angle o =
