The sine of an angle is equal to the ratio of the opposite side to the hypotenuse.

Substitute the name of each side into the definition of the sine function.

Set up the equation to solve for the opposite side, in this case <math><mstyle displaystyle="true"><mi>a</mi></mstyle></math> .

Substitute the values of each variable into the formula for sine.

Combine <math><mstyle displaystyle="true"><mn>5</mn></mstyle></math> and <math><mstyle displaystyle="true"><mfrac><mrow><msqrt><mn>2</mn></msqrt></mrow><mrow><mn>2</mn></mrow></mfrac></mstyle></math> .

The result can be shown in multiple forms.
