TBQ - Height of the cloud — task. Maths TNSB Mentoring, Class 10 Crash course.

The angle of elevation of a cloud from a point '\(h\)' meters above a lake is \(\beta\). The angle of depression of its reflection in the lake is \(45^\circ\). The height of location of the cloud from the lake is:

\(h \left(\frac{1 - \tan \beta}{1 + \tan \beta} \right)\)
\(h \left(\frac{1 + \tan \beta}{1 - \tan \beta} \right)\)
\( h \cos (45^\circ - \beta)\)
none of the above
