Final answer:
Acute angles are those that are less than 90 degrees; examples of acute angles from the provided list are 11.8°, 12.5°, and 14.1°.
Step-by-step explanation:
To name the acute angle below in three different ways, consider that an acute angle is any angle that is less than 90 degrees. Among the angles provided, we can select the ones that fit this criterion. For instance:
These are all examples of acute angles. It's important not only to identify these angles but also to understand that any angle that fits within the range of greater than 0 and less than 90 degrees can be classified as an acute angle.
