You can find a reference about Law of Cosines in your Trigonometry book, and maybe in other sources.

The angle between the 500m and the 461m side is according to this:
, and I call this angle between them to be alpha.

... and keep going until you find this alpha.

Use the same arrangement for every angle in this triangle.
