In a right triangle, if angle $A$ measures $30^ ext{o}$ and the length of the side opposite angle $A$ is $5$ units, what is the length of the hypotenuse of the triangle?
Recall that in a right triangle, the sine of an angle is defined as the ratio of the length of the opposite side to the length of the hypotenuse. Specifically, for angle $A$, this can be written as:
$$ ext{sin}(A) =\frac{ ext{opposite}}{ ext{hypotenuse}}$$
