Finding Side Length in a Right Triangle

In a right triangle, angle $A$ measures $30^{ ext{o}}$ and angle $B$ measures $60^{ ext{o}}$. The length of the side opposite angle $A$ is $5$ units. What is the length of the side opposite angle $B$?

Use the sine function to find the side lengths. Recall that for any angle $ heta$ in a right triangle, the sine function is defined as:

$$ ext{sine}( heta) = rac{ ext{opposite}}{ ext{hypotenuse}}$$

In this case, also remember the relationship between angles and sides in a right triangle.
