The angle of elevation of a cloud from a point h metres above a lake is \(\beta \). The angle of depression of its reflection in the lake is 45°. The height of location of the cloud from the lake is
\(\frac { h\left( 1+tan\beta \right) }{ 1-tan\beta } \)
\(\frac { h\left( 1-tan\beta \right) }{ 1+tan\beta } \)
h tan(45°-\(\beta \))
