1. Let's clarify the problem: we need to find angle $c$ in a triangle or geometric figure. 2. To find angle $c$, we need more information such as the other angles or sides of the triangle. 3. If you provide the measures of the other two angles, we can use the triangle angle sum property: $$c = 180^\circ - a - b$$ where $a$ and $b$ are the other two angles. 4. If you provide side lengths, we can use the Law of Cosines: $$c = \cos^{-1}\left(\frac{a^2 + b^2 - c^2}{2ab}\right)$$ to find angle $c$. 5. Please provide the necessary details to proceed with the calculation.
