CSEC Mathematics · May/June 2015 · Paper 2 · Question 10(a)(i)

The diagram below, not drawn to scale, shows a vertical tower, BT, with a flagpole, TP, mounted on it. A point R is on the same horizontal ground as B, such that RB = 60 m, and the angles of elevation of T and P from R are 35° and 42°, respectively.

Label the diagram to show • the distance 60 m • the angles of 35° and 42° • any right angle(s).
