CSEC Mathematics · May/June 2006 · Paper 2 · Question 11(a)(i)c)

The diagram below, not drawn to scale, shows a vertical tower, FT, and a vertical antenna, TW, mounted on the top of the tower. A point P is on the same horizontal ground as F, such that PF = 28 m, and the angles of elevation of T and W from P are 40° and 54° respectively.

Copy and label the diagram clearly showing any right angles.
