A person standing on the bank of a river observes a tree on the opposite bank at an angle of elevation 60°. If the width of the river is 20 m, find the height of the tree.
Q1. A person standing on the bank of a river observes a tree on the opposite bank at an angle of elevation 60°. If the width of the river is 20 m, find the height of the tree.
Answer: 20√3 m
Explanation: Using tan(60°) = height / 20, we get √3 = height / 20, so height = 20√3 m.
