Question

Find the unknown angle if there are three pair of tangents from P,A and B
and angle APB is 40°?

As in given figure.

Answer 1

Answer:

150

Step-by-step explanation:

since we know that the angle between the two tangents and the angle formed between the radii of two circle are supplementary

Therefore

angle APB + angle QOR = 180

SO ANGLE QOR = 180- 30 = 150
