To find the width the river, a man observes the top of a tower on
the opposite bank making an angle of elevation `61^(@)`. When he
moves `50m` backward from bank and observes the same top of the
tower, his line of vision makes an angle of elevationfo `35^(@)`.
Find the height of the tower and width of the river. `(tan 61^(@)=1.8, 35^(@)=0.7)`

Text Solution

Verified by Experts

The correct Answer is:
