An observer in a hot air balloon sights a building that is 50 m from the balloon's launch point. the balloon has risen 165 m. what is the angle of depression from the balloon to the building? round to the nearest degree
Answers: 3
![\bf tan(\theta)=\cfrac{opposite}{adjacent}\implies tan(\theta)=\cfrac{165}{50} \\ \quad \\ tan^{-1}\left[ tan(\theta) \right]=tan^{-1}\left[ \cfrac{165}{50} \right] \\ \quad \\ \theta=tan^{-1}\left[ \cfrac{165}{50}\right] \\ \uparrow \\ \textit{angle of elevation}\iff\textit{angle of depression}](/tpl/images/0488/3404/cc30f.png)
