P and Q are two observation posts on
the same horizontal ground as the foot R
of a vertical pole RT. P is 2.5 km south
of R. Q is east of R and is on a bearing
of 065° from P. The angle of elevation
of T from P is 40°. Calculate, correct to
three significant figures:
i) sketch the diagram
ii) the distance RT
iii) the distance RO
iv) the distance PQ
v) the angle of elevation of T from Q.​
