if a tree 20 meters tall casts a shadow 30 meters long, what is the angle of elevation from the shadow to the tip of the tree, t

inn [45]

sketch the situation

a trigonometric function that is a relation between the angle of elevation and the 2 sides of the rectangles is the tan

$\tan \theta=\frac{opp}{adj}$ $\tan \theta=\frac{20}{30}=\frac{2}{3}$

find the inverse

$\begin{gathered} \tan ^{-1}(\frac{2}{3})=\theta \\ \theta=33.69º \end{gathered}$

after rounding the angle of elevation is 34º.
