Finding a Side Length in a Triangle Using Trigonometry

In triangle ABC, angle A measures 30 degrees. The side opposite angle A, which is side a, has a length of 5 units. What is the length of side b, which is opposite angle B measuring 60 degrees? Use the sine function to find the length of side b, and express your answer as a decimal to the nearest hundredth.

Recall that the sine function is defined as: $$\sin(\theta) = \f\frac{\text{opposite}}{\text{hypotenuse}}$$
