Question

11. In Fig. 2. PA and PB are tangents to the circle with centre 0 such that
APB = 50°, then the measure of OAB is
​

Answer 1

Answer:

First of all we will go in the triangle of PAB

as PA =PB

x +x + 50= 180

x = 65

OA =OB ( RADIUS)

and radius and tangent are perpendicular

OAP IS 90°

therefore OAP-BAP = 90-65

= 25°.......

ANSWER IS 25°
