Identify the Law of Sines

• $\sin^2x+\cos^2x=1$

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

• $\sin\left(A\right)\sin\left(B\right)\sin\left(C\right)=1$

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

•  $\frac{\sin44}{26}=\frac{\sin\ A}{23}$ 

•  $\frac{\sin\ 26}{44}=\frac{\sin\ 23}{A}$ 

•  $\frac{\sin\ 44}{23}=\frac{\sin\ A}{26}$ 

•  $\frac{\sin23}{44}=\frac{\sin\ 26}{A}$
