The angle of 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:

The angle of elevation of the top 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 30 m vertically above the point A. If the angle of elevation of the top of the tower from B be 30^(@) , then the distance then the distance (in m) of the foot of the tower from the point A is

The angle of elevation of the top of a vertical tower situated perpendicularly on a plane is observed as 60^(@) from a point P on the same plane .From another point Q , 10 m vertically above the point P , the angle of depression of the foot of the tower is 30^(@) The height of the tower is
