You are given the lengths of two sides of a triangle and the angle between these two sides.

Use the cosine rule formula to find the length of the opposite side,
which is under the problem's question.

On the Cosine law, see the lessons

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.
