## A T.V. Tower stands vertically on a bank of a river. From a point on the other bank directly opposite the tower, the angle of elevation of the top of the tower is 60 ∘ . From a point 20 m away this point on the same bank, the angle of elevation of the top of the tower is 30 ∘ . Find the height of the tower and the width of the river.
