Question
A man is standing 30 meters away from the foot of a
tree. The angle of elevation from his eyes to the top of the tree is 60 degrees. Find the height of the tree.Solution
Let the height of the tree be h meters. Using the tangent of the angle of elevation: tan(60°) = h / 30 √3 = h / 30 h = 30√3 meters Thus, the height of the tree is 30√3 meters.
