Sagot :
Consider the schematic diagram given below,
In the diagram, AB represents the height of the tree, and point C is the location of the observer.
The angle of of elevation to the top of the tree is the angle BCA here.
This angle can be calculated as,
[tex]\begin{gathered} \tan (\angle BCA)=\frac{AB}{BC} \\ \tan (\angle BCA)=\frac{45}{20} \\ \tan (\angle BCA)=2.25 \end{gathered}[/tex]Taking the inverse function both sides,
[tex]\begin{gathered} \angle BCA=\tan ^{-1}(2.25) \\ \angle BCA\approx66^{\circ} \end{gathered}[/tex]Thus, the required angle of elevation is approximately 66 degrees.
