Find the Hypotenuse of a Right Triangle

In a right triangle, one of the angles measures 30 degrees. If the length of the side opposite to the 30-degree angle is 4 cm, what is the length of the hypotenuse?

To find the hypotenuse, you can use the relationship in a 30-60-90 triangle, where the sides are in the ratio of 1 : $rac{ oot{3}}{2}$ : $rac{1}{2}$. For the angle of 30 degrees, the side opposite the angle is half of the hypotenuse.
