Finding the Hypotenuse in a Right Triangle

In a right triangle, the angle $ heta$ measures $30^ ext{o}$. If the length of the side opposite to angle $ heta$ is 3 units, find the length of the hypotenuse of the triangle.

Use the sine function: $$ ext{sine}( heta) =\frac{ ext{opposite}}{ ext{hypotenuse}}$$
