Answer 1

angle opq=90-60=30

Step-by-step explanation:

in triangle opq

30 +30+ angle poq=180

angle poq.=120

Answer 2

Answer:

120° is the measure of angle POQ

Step-by-step explanation:

Because, PR is a tangent,

<OPR = 90° (Radius at the point of contact makes 90° at tangent).

<QPR = 60°,

Hence, <OPQ = 90° - 60° = 30°

Also, <OQP = <OPQ = 30° (Angles opposite to equal sides, OP = OQ = r)

In Traingle OPQ

<POQ + 30° + 30° = 180°

=> <POQ = 180° - 60° = 120°
