Hey Alicia :) Remember your Sine Angle Difference Formula?$\Large\rm \sin\left(\color{royalblue}{\alpha}-\color{orangered}{\beta}\right)=\sin\color{royalblue}{\alpha} \cos\color{orangered}{\beta}- \cos\color{royalblue}{\alpha}\sin\color{orangered}{\beta}$

Do you see how we can apply that to our problem here?$\Large\rm \quad?\quad =\sin\color{royalblue}{23} \cos\color{orangered}{27}- \cos\color{royalblue}{23}\sin\color{orangered}{27}$
