To provide you with a distance calculation for the line segment labeled as "C CC", I need more specific details, such as the coordinates of the endpoints of the line segment or a description of the line itself. If you have points in the form of coordinates (like \(C(x_1, y_1)\) and \(C'(x_2, y_2)\)), I can help calculate the distance using the distance formula:
\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \]
Please provide the necessary information, and I'll assist you further!
