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
[tex]\tan \theta=\frac{opp}{adj}[/tex][tex]\tan \theta=\frac{20}{30}=\frac{2}{3}[/tex]
find the inverse
[tex]\begin{gathered} \tan ^{-1}(\frac{2}{3})=\theta \\ \theta=33.69º \end{gathered}[/tex]
after rounding the angle of elevation is 34º.
