In a right triangle, the angle $ heta$ measures 30 degrees. If the length of the side opposite to angle $ heta$ is 5 units, what is the length of the hypotenuse of the triangle?
Use the sine function, which is defined as:
$$ ext{sine}( heta) =\frac{ ext{opposite}}{ ext{hypotenuse}}$$
In this case, you will need to solve for hypotenuse.
