WebSep 15, 2024 · The Law of Cosines can also be used to solve triangles in Case 2 (two sides and one opposite angle), though it is less commonly used for that purpose than the Law of Sines. The following example gives an idea of how to do this. WebNov 17, 2024 · Note that by taking reciprocals, Equation 2.1.1 can be written as. sinA a = sinB b = sinC c , and it can also be written as a collection of three equations: a b = sinA sinB , a c = sinA sin C , b c = sinB sin C. Another way of stating the Law of Sines is: The sides of a triangle are proportional to the sines of their opposite angles.
