law of sines and cosines problem

For this discussion, you will work in groups to solve for
$a$ in the oblique triangle ABC; AB = 30; AC = 15 and angle B =
${20}^{}$

type out the two equations substituting the numbers from the diagram.

• First, type out the Law of Sines set of relationships.
• Next, type out the most appropriate version to use the Law of Cosines for this solution.
• make a prediction of which method will be easier to use in finding a solution and why you think that is the case.
• solve for a using both methods (show step by step work)
