Which of the following angles in standard position is considered to represent a low projection ($\mathrm{elevation}$)?

• A. $45°$
• B. $90°$
• C. $10°$
• D. $75°$

Answer: (C)

Verified step by step guidance

1. Understand that in the context of projections or elevations, a 'low projection' angle refers to an angle that is close to the horizontal axis, meaning it has a small degree measure above 0°.
2. Recall that angles in standard position are measured from the positive x-axis (horizontal axis) counterclockwise, so smaller angles indicate a lower elevation or projection.
3. Compare the given angles: 10°, 45°, 75°, and 90°. Since 10° is the smallest angle, it is closest to the horizontal axis and thus represents a low projection or elevation.
4. Recognize that 90° represents a vertical direction (maximum elevation), and angles like 45° and 75° are intermediate elevations, higher than 10° but lower than 90°.
5. Conclude that the angle with the smallest measure above the horizontal axis (10°) is considered the low projection or elevation.
