Identify the Law of Sines

sin⁡2x+cos⁡2x=1\sin^2x+\cos^2x=1

sin⁡(A)a=sin⁡(B)b=sin⁡(C)c\frac{\sin\left(A\right)}{a}=\frac{\sin\left(B\right)}{b}=\frac{\sin\left(C\right)}{c}

sin⁡(A)sin⁡(B)sin⁡(C)=1\sin\left(A\right)\sin\left(B\right)\sin\left(C\right)=1

Which equation shows how you would use the law of sines to find angle A?

sin⁡4426=sin⁡ A23\frac{\sin44}{26}=\frac{\sin\ A}{23}

sin⁡ 2644=sin⁡ 23A\frac{\sin\ 26}{44}=\frac{\sin\ 23}{A}

sin⁡ 4423=sin⁡ A26\frac{\sin\ 44}{23}=\frac{\sin\ A}{26}

sin⁡2344=sin⁡ 26A\frac{\sin23}{44}=\frac{\sin\ 26}{A}
