I am in a park which has a vertical tower at its centre. The angle of elevation
of the top of the tower at a point A on the ground, due South of the tower, is
60° and the same at a point B on the ground, due West of the point A, is 30°.
If the distance AB = 300 m, the height (in metres) of the tower is?
