To determine the length of CE based on the information provided, we can use a geometric approach if we have a triangle. However, the lengths provided (AB = 12 units and BC = 16 units) do not directly give us a relationship to find CE without knowing the specific configuration or additional information about the points A, B, C, and E.
Assuming there is a right triangle or any other configuration, we need the necessary details to calculate CE. If this is based on a specific concept or theorem (like the triangle inequality or coordinate geometry), please provide that context.
Without additional information, we cannot conclusively determine the length of CE from the options provided. If there are specific geometric relationships or the arrangement of points A, B, C, and E, please share that to help clarify the problem.
