A balloon is rising vertically upwards. ...

A balloon is rising vertically upwards. An an instant, an observation on the ground, whose distance from the balloon is 100 meters, sees the balloon at an angle of elevation of `30^(@)`. If the balloon rises further vertically to a point where the angle of elevation as seen by the observer is `45^(@)`, then its height (in meters) from the ground is
