A person standing on the bank of a river observes that the angle subtended by a tree on the opposite bank is 60°. When he retreats 20 m from the bank, he finds the angle to be 30°. Find the height of the tree.
Q1. A person standing on the bank of a river observes that the angle subtended by a tree on the opposite bank is 60°. When he retreats 20 m from the bank, he finds the angle to be 30°. Find the height of the tree.
Answer: 10√3 m
Explanation: Using trigonometric ratios and the given angles, we can form equations to solve for the height of the tree.
