Answer 2

Answer:

The correct answer is option (C) 100°

Step-by-step explanation:

We can see that POQR is a quadrilateral,

And sum of interior angles of a quadrilateral is 360°.

Now, angle OPR = 90°,

and Angle OQR = 90°,

( The radius is perpendicular to the tangent at the point of contact )

Now,

angle OPR + angle OQR + angle QOP + angle PRQ = 360°

90 + 90 + 80 + angle QOP = 360

angle QOP = 360 - (180 + 80) = 360 - 260 = 100°
