Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I was wondering how one would go about finding the direction of the resultant of three vectors, when performing a vector addition of three vectors. I mean I know how to find the magnitude, by summing all the squares of the component vectors, i and j, and square rooting that sum, but how does one get the direction of that third vector? The whole thing forms a polygon, for god's sake.
