State whether you would use the Law of Cosines or the Law of

State whether you would use the Law of Cosines or the Law of Sines to initially start a solution. The three side - angle known values are given. a, C, A Law of a, b, A Law of b, c, A Law of b, A, C Law of A, B, a Law of a, b, c Law of

Solution

1) a, C , A = law of sines ( a / sin A = c/ sin C )

2) a,b,A = law of sines ( a/ sin A = b / sin B )

3) b,c , A = law of cosines ( a^2 = b^2 + c^2 - 2bc cos A )

4) b, A, C = law of sines

5) A,B,a = law of sines

6) a,b,c = law of cosines
