In the diagram, PQ and PS are tangents to the circle O. If PSQ = m, <SPQ = n and <SQR = 33\(^o\), find the value of (m + n)

  • A 103\(^o\)
  • B 123\(^o\)
  • C 133\(^o\)
  • D 143\(^o\)

The correct answer is B. 123\(^o\)

< SQP = 180 - (90 + 33)  < on a ----

= 180 - (123)

= 57\(^o\)

Therefore, (m + n) = 123\(^o\)
