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. WebLearn about arcsine, arccosine, and arctangent, and how they can be used to solve for a missing angle in right triangles. Let's take a look at a new type of trigonometry problem.
