This is the basic and conceptual question from trigonometry in which we have to find the height of the tower when from the top of a vertical tower , the angles of depression of two cars , in the same straight line with the base of tower , at an instant are found to be 45 and 60 . If the cars are 100 m apart and are on the same side of the tower.
