seconds, he observed the bird flying at the same height at an angle of elevation of 30° and
the ball flying towards him at the same height at an angle of elevation of 60°.
(i) At what distance from the foot of the tree was he observing the bird sitting on the
tree?
(ii) How far did the bird fly in the mentioned time?
