Ambiguous case law of sines two triangles SSA

The video tutorial explores solving a triangle problem using the side-side-angle method. It discusses the possibility of multiple triangles and applies the Law of Sines to find missing angles. The instructor explains the concept of inverse sine and its implications, emphasizing the need to consider both acute and obtuse angles. The lesson concludes with a case analysis of different triangle possibilities and hints at future topics.
