PQR is a triangular park with $\displaystyle \mathrm{PQ}=\mathrm{PR}=200 \mathrm{~m}$. A T.V. tower stands at the mid-point of QR. If the angles of elevation of the top of the tower at P, Q and R are respectively $\displaystyle 45$°, $\displaystyle 30$° and $\displaystyle 30$°, then the height of the tower (in m) is :
