Best ResponseYou've already chosen the best response.0I apologize for the poor drawing. I know that I use tangent so it would be: tan(theta)=.5952 but I don't know how to get degrees after that.

Best ResponseYou've already chosen the best response.0SOHCAHTOA you have an opposite side to that angle and an adjacent one. The ratio you need to use is `TOA` = \(\tan(\theta) = \dfrac{17.5}{29.4}\)

Best ResponseYou've already chosen the best response.0So naturally to find the missing angle we take the arctan function. \[\theta = \tan^{1}\left(\frac{17.5}{29.4}\right)\]

Best ResponseYou've already chosen the best response.0\[\tan \theta=\frac{ 17.5 }{ 29.4 },\theta=\tan^{1} \frac{ 17.5 }{ 29.4 }=30.76~ degree\]
