TR is the tangent to the circle PQR with centre O. Find the size of ∠PRT

  • A.
    44o
  • B.
    46o
  • C.
    60o
  • D.
    74o
  • E.
    118o
Correct Answer: Option C
Explanation

Reflex < POQ = 360° – 148° = 212°

< PRO = 360° – 330° = 30°

But < ORT = 90° (implies) < PRT = 90° – 30° = 60°
