How to Find Any Angle in a Triangle Using Only the Sides (Law of Cosines)
Learn how to find an unknown angle in any triangle when all three side lengths are known using the Law of Cosines. In this step-by-step math tutorial, we solve for a missing angle in a non-right triangle and explain how to know when to use the Law of Cosines instead of the Law of Sines. In this video, you’ll learn: • How to identify when to ...
