The angle of elevation of the top P of a vertical tower for a person standing at a point $\displaystyle A$ on the horizontal ground due north of the tower is $\displaystyle 45^{\circ}$. Another person $\displaystyle B$ is standing $\displaystyle 50$ m west of $\displaystyle A$ on the ground. If the angle of elevation of $\displaystyle P$ at $\displaystyle B$ is $\displaystyle 30^{\circ}$ then the height (in meters) of the tower is
