WebLet us assume that we want to find the angle A. For this, we need to know the length of the opposite side ‘a’, and another angle-side pair such as angle B and the side b, or angle C and the side c. The calculations follow the side-side-angle (SSA) theorem. The Law of Sines is used for the calculations of the other unknowns.
Web6 apr. 2024 · The law of cosines is used when the lengths of two sides and the angle between them is given. Using the law of cosines, the length of the third side can be calculated. Using the lengths of the three sides, we can apply Heron’s formula and obtain the area of the triangle.
