The angle of elevation of the top point P of the vertical tower PQ of height h from a point A on the ground is 45∘ and from a point B, the angle of elevation is 60∘, where B is a point at a distance d from the point A, measured along the line AB, which makes an angle 30∘ with AQ. prove that d = h(√3−1) |
