P and Q are two observation posts on the same horizontal ground as the foot R of a vertical pole RT. P is 2.5km south of R. Q is east of R and on a bearing of 065° from P. The angle of elevation of T from P is 40°. Calculate, the angle of elevation of T from Q.

Answer 1

RT = 2.5 tan40°
RQ = 2.5 tan65°
so,
tan <RQT = RT/RQ
