CSEC Mathematics · January 2012 · Paper 2 · Question 10(b)(ii)c)

The diagram below, not drawn to scale, shows a vertical pole, PL, standing on a horizontal plane, KLM. The angle of elevation of P from K is 28°, KL = 15 m, LM = 19 m and ∠ KLM = 115°.

Calculate, giving your answer to 2 significant figures, the angle of elevation of P from M.
