WebFeb 18, 2024 · The Law of Sines Formula or Sine rule is understood as the ratio of sides and equivalent angles of a given triangle. The law of sines formula is generally used to evaluate the unknown sides or angles off an oblique triangle. The mathematical formula of the law of sines is given as where, a, b and c are the sides of the triangle. WebTo derive the formula, erect an altitude through B and label it h B as shown below. Expressing h B in terms of the side and the sine of the angle will lead to the formula of the sine law. sin A = h B c. h B = c sin A. sin C = h B a. …
