The Law of Cosines has a long history. In more recent times, the relationship has played a central role in surveying, navigation, and other fields that depend on the principle of triangulation. The Law of Cosines may be used to solve a triangle given either of the following: 1. two side lengths and the included angle measure (SAS) 2. three side lengths (SSS)The Law of Sines allows you to find the unknown measures for a given triangle, as long as you know either of the following: 1. Two angle measures and any side length—angle-angle-side (AAS) or angle-side-angle (ASA) information 2. Two side lengths and the measure of an angle that is not between them—side-side-angle (SSA) information1-Conduct a scientific research about this case (SSA) You can answer following question to help you and your researchA.which mathematician (if any) introduced this technique (case)B.what do we mean by Ambiguous CaseC.how many cases do we have and what are they, ExplainD.Compare this case with other cases, what do we need and how to solve2-Provide two different examples you can use Ambiguous Case to evaluate the triangle3- Provide one example about all other cases (SAS, SSS, AAS and ASA) to evaluate the triangle
