**The Law of Cosines**

For triangle ABC with sides \(a\), \(b\), and \(c\), the Law of Cosines states the following:

\[ c^2 = \]

The equation box is empty, indicating an incorrect or missing answer, as shown by the red cross symbol next to it.

**Explanation of the Law of Cosines**

The formula for the Law of Cosines is:

\[ c^2 = a^2 + b^2 - 2ab \cdot \cos(C) \]

where \(C\) is the angle opposite side \(c\).

This law is useful for finding the third side of a triangle when two sides and the included angle are known, or determining an angle when all three sides are known.
