A tower PQ stands on a horizontal ground with base Q on the ground. The point R divides the tower in two parts such that $\displaystyle \mathrm{QR}=15 \mathrm{~m}$. If from a point A on the ground the angle of elevation of R is $\displaystyle 60$° and the part PR of the tower subtends an angle of $\displaystyle 15$° at A, then the height of the tower is :
