Content:

Solve for α in the oblique triangle ABC; AB = 30; AC = 15 and angle B = 20°
1 Type out the two equations substituting the numbers from the diagram.
2 Type out the Law of Sines set of relationships and type out the most appropriate version to use the Law of Cosines for this solution.
3 Solve for a using both methods (show step by step work)
Solution
1 The sum of all angles of a triangle adds up to 180o
A+B+C = 180, and B = 20
A+20+C = 180
A + C = 160
