Textbook Problem

At a horizontal distance of 45 m from the bottom of a tree, the angle of elevation to the top of the tree is 26°. How tall is the tree? (See Section 1.8.)

Expert Solution
To determine
The height of the tree.

Explanation of Solution

Given info:

Horizontal distance to the tree is 45 m and the angle of elevation to the top of the tree is 26° .

From the figure the formula to calculate the height of the tree is,


  • L is the horizontal distance
  • H is the height of the tree
  • θ is angle of elevation to the top of the tree

Substitute 45 m for L and 26° for θ to find H
