3. A balloon is observed from two stations A and B at horizontal level, A being 1000m north of B. At a given instant the bearing of the balloon from A is 33.2° and its angle of elevation is 53.42°, while from B its bearing is 21.45. Calculate the height of the balloon. In the figure, a balloon is at P, and Q is directly below P. 0=33.2, e=21.45, a = 53.42 andd = 500m. same
