Answer:

  y = 60

Step-by-step explanation:

The figure given is a parallelogram;

    opposite angles in a parallelogram are equation;

     So;

         <POR  = <PQR

<POR = 2y - 60

<PQR = y

Therefore;

            2y - 60 = y

             -60  = y - 2y

             -60 = -y

                y = 60
