Final answer:
Without additional context or a diagram, we can only infer that angles °AFC and °CFE might be supplementary since the sum of angles in a triangle is 180 degrees. To fully determine their relationship, a diagram illustrating these angles is required.
Step-by-step explanation:
To determine what terms describe the angles °AFC and °CFE, we must consider the sum of their measures and compare with the definitions of complementary, acute, supplementary, and obtuse angles.
Angles are complementary if they add up to 90 degrees. They are acute if each angle is less than 90 degrees. Angles are said to be supplementary if their sum is 180 degrees, which is also the total sum of angles in a triangle as per your knowledge. An angle is obtuse if it is more than 90 degrees but less than 180 degrees.
If angles °AFC and °CFE are part of the same triangle, then by taking into account that the sum of the angles in a triangle is always 180 degrees, we can conclude that these angles are supplementary if they add up to this total. Without more information, we cannot definitively state if they are acute or obtuse, but we know they cannot be complementary as that would mean they would sum up to only 90 degrees.
However, to provide a definitive answer to the student's question, additional context or a diagram showing angles °AFC and °CFE would be necessary, as angles within different geometric shapes or figures can have different relationships.
