Geometry

The angle of elevation of a cloud from a point $h$ meters above a lake is $\theta$ . The angle of depression of its reflection in the lake is $45^{\circ}$ . Find the height of the cloud in meters.

h\cot(90^{\circ}+\theta)

h\cot(90^{\circ}-\theta)

h\tan(45^{\circ}-\theta)

h\tan(45^{\circ}+\theta)
