Finding Side Length Using Law of Sines

Hard Preparing For Higher Math Geometry

In a triangle ABC, angle A measures 45 degrees, angle B measures 60 degrees, and side a (the side opposite angle A) measures 8 units.

Using the Law of Sines, calculate the length of side b (the side opposite angle B).

Recall that the Law of Sines states that $$\f\frac{a}{\sin(A)} = \f\frac{b}{\sin(B)}$$.
