WebThe Law of Sines establishes a relationship between the angles and the side lengths of ΔABC: a/sin (A) = b/sin (B) = c/sin (C). The relationship explains the plural "s" in Law of Sines: there are 3 sines after all. Another important relationship between the side lengths and the angles of a triangle is expressed by the Law of Cosines. Web10 apr. 2024 · 10. Mini Golf.
