1. A balloon B is observed simultaneously from two points P and Q on a horizontal Ground. P is at a distance of c meters due north of Q. R is the projection of B on the ground . The bearings f the balloon from P and Q are Sα°E and Nβ°E respectively. The angle of elevation of B from P is θ°.
(b)Given that θ=40, α=54 and β=46, find
(i) h/c,
(ii)the angle of elevation of B from Q,
(III) the angle of elevation and the bearing of B from M, where M is the mid-point of PQ.
