From a point on the line joining the feet of two poles of equal heights the angles
of elevation of the top of the pole are observed to be 30 and 60 . If the distance
between the feet of the poles is 32 feet find; |
(i) heights of the poles
(ii) the position of the point of observation. |

| AB is a straight road leading to C, the foot of the tower. A is at a distance of
200 yards from C and B at 75 yards from C. If the angle of elevation of the tower
at B be double the angle of elevation at A, find the height of the tower? |
