Finding Length of Side using Law of Sines

Medium Additional Topics In Math Trigonometry

In triangle ABC, angle A measures 30 degrees and side a (opposite angle A) measures 10 units. To find the length of side b (opposite angle B), use the Law of Sines, which states:

$$\frac{a}{\sin A} = \frac{b}{\sin B}$$

Given that angle B measures 45 degrees, calculate the length of side b. Report your answer as a decimal rounded to two decimal places.
