A balloon is slanting down in a straight line passes vertically above two points A and B on a horizontal plane 1000 meters apart. When above A it has an altitude `60^(@)` as seen from B and when above B, altitude is `30^(@)` as seen from A. What is the distance of the point from point A where the balloon strike the plane.

500 m

`1000sqrt(3)` m
