Question 295736
<font face="Garamond" size="+2">

The tangent of an angle is the measure of the opposite side of the triangle divided by the adjacent side of the triangle.  So, you want to know the angle who's tangent is *[tex \LARGE \frac{200}{50}=4], or 


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \tan^{-1}(4)]


The calculator, in Degrees mode, says:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \tan^{-1}\,(4)\ \approx\ 75.963756532073521417107679840837]


or 


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 76\ ]degrees, to the nearest degree.
