Calculate Hypotenuse of Right Triangle with 30 Degrees

Easy Additional Topics In Math Trigonometry

Consider a right triangle where one angle measures $30^{ ext{o}}$. In this triangle, the length of the side opposite the $30^{ ext{o}}$ angle is 5 units. What is the length of the hypotenuse of this triangle?

Use the sine function, which for an angle $ heta$ in a right triangle is defined as:

$$ ext{sine}( heta) =\frac{ ext{opposite}}{ ext{hypotenuse}}$$
