Use the cosine law.

If you are not familiar with it, learn about it from the lessons

    - Proof_of_the_Law_of_Cosines_Revisited
    - Solve triangles using Law of Cosines

in this site.

In addition to the theory, clearly explained, you will find there many solved problems, that are your TEMPLATES.

Consider these lessons as your handbook, textbook, guidelines, tutorials and (free of charge) home teacher.

Happy learning (!)
