WebSep 10, 2024 · Suppose you have a triangle ABC as in the figure: Since the angles A + B + C = π, these are the internal angles of a general triangle. Using the law of cosines, you can write: a2 = b2 + c2 − 2bccosAb2 = a2 + c2 − 2accosBc2 = a2 + b2 − 2abcosC It follows from here that: cosA = a2 − b2 − c2 − 2bc cosB = b2 − a2 − c2 − 2ac cosC = c2 − a2 − b2 − 2ac WebApr 17, 2024 · Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries.
