In the diagram, RT is a tangent to the circle at R, < PQR = 70\(^o\), < QRT = 52\(^o\), < QSR and < PRQ = x. Calculate the value of x.

  • A 70\(^o\)
  • B 58\(^o\)
  • C 55\(^o\)
  • D 48\(^o\)

The correct answer is B. 58\(^o\)

x = 180\(^o\) - (52\(^o\) + 70\(^o\))

= 180\(o\) - 122\(^o\)

= 58\(^o\)
