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, tan35^(@)=0.7)`

Text Solution

Verified by Experts

The correct Answer is:
height of the tower `=57.28m` and width of the river `=31.82m`
