Finding the Hypotenuse in a Right Triangle

Easy Additional Topics In Math Trigonometry

In a right triangle, one of the angles measures $30^{ ext{o}}$. If the length of the side opposite to this angle is 5 units, what is the length of the hypotenuse of the triangle? Use the sine function to solve the problem.

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. The sine function for a $30^{ ext{o}}$ angle is a common reference value.
