Calculate Side Length in Triangle Using Law of Sines

Very Hard Additional Topics In Math Trigonometry

In triangle ABC, angle A measures $30^{ ext{°}}$, and side a, which is opposite angle A, measures 10 units. Angle B measures $60^{ ext{°}}$. Calculate the length of side b, which is opposite angle B. Use the Law of Sines, which states that:

$\f\frac{a}{\sin(A)} = \f\frac{b}{\sin(B)} = \f\frac{c}{\sin(C)}$
