Final answer:
All listed angles (11.8°, 12.5°, 14.1°, 19.2°, 24.2°, 25.7°, 29.1°, and 41.0°) are acute angles since they are each less than 90 degrees. Acute angles are significant in various contexts, including physics and geometrical measurements.
Step-by-step explanation:
To determine which angles are acute, we must first recall that an acute angle is one that is less than 90 degrees. Given your examples:
- 11.8°
- 12.5°
- 14.1°
- 19.2°
- 24.2°
- 25.7°
- 29.1°
- 41.0°
All of these angles are acute angles because they are all less than 90 degrees. It's also worth noting that in physical phenomena, such as interference patterns, angles can't be greater than 90°, so this context reinforces that these figures are acute angles. Angles are also important in other concepts like the measurement of time using a clock, where the angles between the hands represent different times, or in angular acceleration, such as the rotation of a clock's second hand.
