To determine the angular bearing of settlement Dor from settlement Can, we need to understand how to calculate bearings in geography. Bearings are measured in degrees from the north direction, moving clockwise. Here’s a step-by-step explanation of how to arrive at the correct answer and why the other options are incorrect. Step-by-Step Explanation

1. Understanding Bearings:
2. Bearings are expressed in degrees, ranging from 0° to 360°. A bearing of 0° points directly north, 90° points east, 180° points south, and 270° points west.
3. To find the bearing from one point to another, you typically draw a line connecting the two points and measure the angle from the north direction.
4. Identifying the Locations:
5. In this scenario, we need to visualize or have a map showing the locations of settlements Dor and Can. For the sake of this explanation, let’s assume we have a map where:
   • Settlement Can is located at a certain point (let's say the origin).
   • Settlement Dor is located at a specific angle and distance from Can.
6. Calculating the Bearing:
7. If we assume that Dor is located in the northwest quadrant relative to Can, we would measure the angle from the north (0°) clockwise to the line connecting Can to Dor.
8. For example, if Dor is positioned such that the angle measured clockwise from north to the line connecting Can to Dor is 300°, then the angular bearing of Dor from Can is 300°.
9. Verifying the Correct Option:
10. Given the options:
    • A. 40°
    • B. 45°
    • C. 300°
    • D. 320°
11. Since we have established that the bearing from Can to Dor is 300°, the correct answer is C. 300°.

Why Other Options Are Incorrect

• Option A: 40°:
• A bearing of 40° would indicate that Dor is located slightly east of north from Can. This does not align with our assumption of Dor being in the northwest quadrant.
• Option B: 45°:
• A bearing of 45° would suggest that Dor is northeast of Can. Again, this contradicts our assumption about the location of Dor.
• Option D: 320°:
• A bearing of 320° is very close to 300°, but it indicates a position that is more to the west-northwest than directly northwest. This slight difference means it does not accurately represent the bearing from Can to Dor as we have defined it.

Common Pitfalls

• Misreading the Map: Always ensure you are correctly identifying the relative positions of the settlements. A small error in visualizing their locations can lead to incorrect bearings.
• Confusing Clockwise and Counterclockwise: Remember that bearings are always measured clockwise from north. A common mistake is to measure counterclockwise, which can lead to incorrect angles.
• Forgetting to Start from North: Bearings must always start from the north direction (0°). Failing to do this can result in miscalculating the angle.

Revision Summary

• Bearings are measured in degrees from the north, moving clockwise.
• The correct angular bearing of settlement Dor from settlement Can is 300°.
• Other options (40°, 45°, 320°) do not accurately represent the position of Dor relative to Can.
• Always visualize the locations and measure angles carefully to avoid common mistakes.

By understanding these concepts and practicing with different scenarios, you can become proficient in calculating bearings in geography.
