The angle of elevation of a cloud from a point h metres above a lake is β. The angle of depression of its reflection in the lake is 45°. The height of location of the cloud from the lake is
(1) \(\frac{h(1\,+\,tan\beta)}{1\,-\,tan\beta}\)
(2) \(\frac{h(1\,-\,tan\beta)}{1\,+\,tan\beta}\)
(3) h tan(45° - β)
(4) none of these
