none
Since opposite angles in a parallelogram are equal, we know that m<R = m<P = 180 - 30 = 150 degrees. Therefore, the sum of the interior angles of triangle PQR is 180 + 150 + 150 = 480 degrees. Since triangle PQR is isosceles (PQ=QR) we have m<Q = (180 - 480/2)/2 = 30 degrees. Therefore, the answer is 30 degrees.
So the answer is none of the options provided.
