What are degrees of an arc from 0 to 360 used for precise directions?

• A. Azimuths
• B. Elevation
• C. Slope
• D. Sector Reference System

Answer: (A)

Azimuths are angular measurements used to specify a direction on the horizontal plane. They use degrees from 0 to 360, measured clockwise from a reference direction (usually true north or magnetic north). This provides a precise, unambiguous way to say exactly which way to point toward a target, which is essential in navigation, surveying, and map reading. For example, 90 degrees points due east, 180 degrees points due south, and 270 degrees points due west. Elevation describes how high above the horizon something is, not which way it lies on the ground. Slope is the steepness of a surface, not a horizontal direction. The term Sector Reference System isn’t the standard way to express compass direction with 0–360 degrees.
