Equations

solve for α 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.
Write both equations and make a prediction of which method will be easier to use in finding a solution and why you think that is the case.
