Question
From a point T, a tangent TP at point P is drawn to a circle with centre O. A secant TQR (point Q is near to point T) is drawn from the point T. Triangle PQR is inscribed in the circle by joining points P, Q, and R. Lines OQ and OR are drawn. If ∠PTQ = 27° and ∠TPQ = 55°, what is the degree measure of ∠ROQ?
