Answer:

The value of x and y is;


\begin{gathered} x=12 \\ y=24 \end{gathered}

Step-by-step explanation:

Given the Triangle in the attached image.

To get the value of x and y. Let us apply trigonometry;


\sin \theta=(opposite)/(Hypotenuse)

For x;


\begin{gathered} \sin 45=\frac{x}{12\sqrt[]{2}} \\ x=12\sqrt[]{2}\sin 45 \\ \sin 45=\frac{1}{\sqrt[]{2}} \\ So; \\ x=12\sqrt[]{2}*\frac{1}{\sqrt[]{2}} \\ x=12 \end{gathered}

Now, that we have the value of x, let us solve for y;


\begin{gathered} \sin 30=(x)/(y) \\ y=(x)/(\sin 30) \\ x=12\text{ and }\sin 30=0.5 \\ So; \\ y=(12)/(0.5) \\ y=24 \end{gathered}

Therefore, the value of x and y is;


\begin{gathered} x=12 \\ y=24 \end{gathered}
