Two stations due south of a leaning towe...

Two stations due south of a leaning tower which leans towards the north are at distances a and b from its foot If `alpha` and `beta` are the elevations of the top of the tower from these stations then prove that its inclination `theta` to the horizontal is given by `cottheta =(bcotalpha-acotbeta)/(b-a)`

A

`(b cotx+a coty)/(b-a)`

B

`(b cotx-a coty)/(b-a)`

C

`(a cotx-b coty)/(b+a)`

D

None of these
