How would you describe a target 1200 meters away on a bearing of 065 degrees in polar coordinates?

• A. 1.2 kilometers at a bearing of 65 degrees from the observer.
• B. Range 1200 meters, Azimuth 065 degrees.
• C. Azimuth 060 degrees, Range 1200 meters.
• D. The target location described by polar coordinates is Range 1.2 kilometers and Azimuth 70 degrees.

Answer: (B)

Describing a target in polar coordinates means stating how far away it is (the range) and in what direction from the observer (the azimuth). The distance is the range, and the direction is the azimuth measured clockwise from north. A bearing of 065 degrees is the same as an azimuth of 65 degrees, and 1200 meters is 1.2 kilometers. The standard polar-coordinate description uses Range first, then Azimuth with clear units: Range 1200 meters, Azimuth 065 degrees. While other options convey the same information in different phrasing, they don’t align with the conventional polar-coordinate format or contain the exact required values (wrong azimuth or unit presentation), so this one best fits the standard.
