What letters are at these coordinates? a. \( 20^{\circ} 10^{\prime} \mathrm{N}, 71^{\circ} 30^{\prime} \mathrm{W} \) b. \( 20^{\circ} 20^{\prime} \mathrm{N}, 72^{\circ} 00^{\prime} \mathrm{W} \)

To determine the letters at the given coordinates, we need to identify the locations corresponding to the specified latitude and longitude. ### Step 1: Identify the Locations a. **Coordinates**: \( 20^{\circ} 10^{\prime} \mathrm{N}, 71^{\circ} 30^{\prime} \mathrm{W} \) - **Latitude**: \( 20^{\circ} 10^{\prime} \mathrm{N} \) is approximately in the Caribbean region, specifically near the coast of Venezuela. - **Longitude**: \( 71^{\circ} 30^{\prime} \mathrm{W} \) places it further west, likely near the northern coast of South America. b. **Coordinates**: \( 20^{\circ} 20^{\prime} \mathrm{N}, 72^{\circ} 00^{\prime} \mathrm{W} \) - **Latitude**: \( 20^{\circ} 20^{\prime} \mathrm{N} \) is also in the Caribbean region, slightly further north than the previous coordinates. - **Longitude**: \( 72^{\circ} 00^{\prime} \mathrm{W} \) indicates a position further west, likely still in the vicinity of the Caribbean Sea. ### Step 2: Determine the Letters To find the letters associated with these coordinates, we typically refer to a specific mapping or grid system that assigns letters to geographic locations. This could be a grid used in a game, a specific mapping system, or a reference to a known set of coordinates. Without a specific mapping system provided, I cannot directly determine the letters at these coordinates. If you have a specific context or mapping system in mind (like a game board, a specific grid, etc.), please provide that information so I can assist you further.
