Finding the Hypotenuse in a Right Triangle

In a right triangle, one of the angles measures $30^{ ext{°}}$. If the length of the side opposite the $30^{ ext{°}}$ angle is $5$ units, what is the length of the hypotenuse?

Using the trigonometric rules for a right triangle, recall that in a $30^{ ext{°}}$-$60^{ ext{°}}-$90^{ ext{°}} triangle, the ratios of the lengths of the sides are $1 :\frac{ ext{√3}}{2} : 2$.
