How to solve for x in a triangle with 2 sides
WebNov 19, 2024 · Well, when you have two angles of a triangle you can find the third one easily: A + B + C = 180° C = 180° − A − B In this case, C = 180° − 31° − 42° = 107°. For the third side, there are a couple of ways to go. You wrote expressions above for AD and DB, and you know that c = AD+DB, so you could compute c = b cos A + a cos B. WebIn Other Forms Easier Version For Angles. We just saw how to find an angle when we know three sides. It took quite a few steps, so it is easier to use the "direct" formula (which is just a rearrangement of the c 2 = a 2 + b 2 − 2ab cos(C) formula). It can be in either of these forms:
