The angle fo elevation of the loop of a ...

The angle fo elevation of the loop of a vertical tower standing on a horizontal plane is observed to be `45^(@)` from a point `A` on the plane. Let `B` be the point `30m` vertically above the point `A`. If the angle of elevation of the top of the tower from `B` be `30^(@)`, then the distance (in m) of the foot of the lower from the point `A` is:

A

`15 (3 + sqrt(3))`

B

`15 (5 - sqrt(3))`

C

`15 (3 - sqrt(3))`

D

`15 (1 + sqrt(3))`
