Answer:

Step-by-step explanation:

in triangle PQR and PMR

angle PMR = RPQ.......both 90'

          angle R=R       common angle

so triangle PQR is similar to PMR

therefore   MR/PR =PR/QR      (cpct)

                   4.5*8=PR*PR

                      PR*PR=36

                          PR=6
