The angle of elevation of a cloud from a point \(h\) meters above a lake is \(\theta\) (let us use standard board values:\(30^\circ\) from a point \(50\ m\) above the lake) and the angle of depression of its refelction in the lake is \(60^\circ\). Obtain the height of the cloud above the lake.
The heigth of the cloud above lake is \(m\).
