I'm trying to solve a physics problem concerning phasor additions, but unfortunately it seems I've forgotten most of my pre-calc maths, especially geometry.(adsbygoogle = window.adsbygoogle || []).push({});

Given a irregular quadrilateral with 3 of its sides of known length, and the values of 2 of its interior angles (specifically the angles formed at the junction where 2 of the 3 known sides meet), is there any way where I may determine the length of the unknown side? Or do I require more information?
