In the diagram, P, Q, R and S are four points lying
on horizontal ground. RT represents a slanting
lamp post. The angles of elevation of the top of the
lamp post from P, Q and Sare 42°, 62° and 56°
respectively. PQ= 3.4 m and RS= 2.9 m, calculate
the length of the lamp post. Hence determine the
angle which the lamp post makes with the vertical
