Solve the following question:(1) A person is stading at a distance of 80 m from a church looking at its top. The angle of elevation is of 45^@ . Find the height of the church.

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)
