A parachutist is descending vertically and makes angles of elevation of \( 45^{\circ} \) and \( 60^{\circ} \) at two observing points \( 100 \mathrm{~m} \) apart from each other on the left side of himself. Find the maximum height from which he falls and the distance of the point where he falls on the ground from the just observation point.
