O is the centre of the circle PQRS. PR and QS intersect at T POR is a diameter, ∠PQT = 42o and ∠QTR = 64o; Find ∠QRT
  • A.
    68o
  • B.
    64o
  • C.
    42o
  • D.
    32o
  • E.
    22o.
Correct Answer: Option A
Explanation

TQR = 90 – 42 = 48o
QRT = 180 – (64 – 48)
&nbsp&nbsp&nbsp = 180 – 112
&nbsp&nbsp&nbsp&nbsp= 68o
