The angles of depression and elevation of the top of a wall 11 m high from top and bottom of a tree are 60° and 30° respectively. What is the height of the tree?
Let DC be the wall, AB be the tree.
Given that angleDBC = 30°, angleDAE = 60°, DC = 11 m
BC = 11√3m
AE = BC =11√3m?(1)
[? Substituted value of AE from (1)]
Height of the tree
= AB = EC = (ED + DC)
= (33 + 11) = 44 m
