Webcentury. Both the famous Laws of Sines and Cosines are used extensively in surveying, navigation, and other situations that require triangulation of non-right triangles. In this … Web22 feb. 2024 · The law of sines formula is used to relate the lengths of a triangle’s sides to the sines of consecutive angles. It is the ratio of the length of the triangle’s side to the sine of the angle generated by the other two remaining sides. Except for the SAS and SSS triangles, the law of sines formula is applied to every triangle.
