Two ranging rods, one of 3.00 m and the other of 1.50 m length, were used in the effort to find the height of an inaccessible tower. In the first setting the rods were so placed that their tops were in line with the top of the tower.

Two ranging rods, one of 3.00 m and the other of1.50 m length, were used in the effort to find the height of an in accessible tower. In the first setting the rods were so placed that their tops were inline with the top of the tower. The distance between the rods was 15 m .In the second setting the rods were ranged on the same line as before. This time the distance between the rods was 30 m. If the distance between the two longer rods was 90 m, find the height of the tower

A river is flowing from west to east. For determining the width of the river two points A and B are selected on southern bank such that distance AB = 75 m. Point A is westwards. The bearings of a tree C on the northern bank are observed to be 38° and 338° respectively from A and B. Calculate the width of the river.
