Rounding correctly for the law of cosines

The video tutorial covers solving triangle problems using the law of sines and cosines. It begins with an introduction to isosceles triangles and the purpose of the example. The instructor demonstrates how to apply the law of cosines to find a side length, followed by calculations and error handling. The law of sines is then used to find other side lengths, considering angle properties. The tutorial concludes with final calculations and remarks on triangle properties.

Describe the process of finding the other angles in the triangle after determining one side length.
