From the top of a cliff of height a, the angle of depression of the foot of a certain tower is found to be double the angle of elevation of the top of the tower of height h. If `theta` be the angle of elevation, then prove that
`tan theta = sqrt(3-(2h)/(a))`.

A

`sin^(-1) sqrt(x//(2-h))`

B

`tan^(-1) sqrt(3-2h//x)`

C

`sin^(-1) sqrt(2h//x)`

D

`cos^(-1) sqrt(2h//x)`
