Find $QR$ . A triangle Q S T is drawn. A line pass through vertex T intersects the side Q S at point R. Angle T R Q is marked right angle. Length of side Q T is labeled 4.7, length of side T S is labeled 4.7 and length of segment R S is labeled 1.3.

What point is the projection of q on a) r b) s c) t
