Expert Answer:
A person sees the top of a tree on the bank of a river at an angle of elevation of 70o. Stepping 20 metres back, the angle of elevation becomes 55o. Height of the person is 1.4 m.
We need to draw a rough figure and find:
(i) Height of the tree
(ii) Width of the river

- If two crows are sitting at a height of 15 m and 10 m on different trees vertically opposite to each other. They view a vaddi (an estable) on the ground at a angle of depression 45°and 60° respectively. They start at the same time and fly at the same speed along the shortest path to pick up the vadai.Which bird will succeed in it.?
