To determine the bearing of Jata from Adaba, we need to understand what a bearing is and how to calculate it. A bearing is a direction or path along which something moves or along which it lies, typically expressed in degrees from North (0°) in a clockwise direction. Step-by-Step Explanation

1. Understanding Bearings:
2. Bearings are measured in degrees from the North direction. For example, a bearing of 90° means the direction is due East, while a bearing of 180° means it is due South.
3. Identifying the Locations:
4. In this scenario, we have two locations: Adaba (the starting point) and Jata (the destination). To find the bearing from Adaba to Jata, we need to visualize or plot these two points on a map or coordinate system.
5. Plotting the Points:
6. If we assume that Adaba is at a certain coordinate (let's say the origin for simplicity) and Jata is located at a specific angle and distance from Adaba, we can use trigonometric principles to find the bearing.
7. Calculating the Bearing:
8. To find the bearing, we would typically measure the angle from the North line (vertical line pointing upwards) to the line connecting Adaba to Jata. This angle is what we refer to as the bearing.
9. If we have a map or a coordinate system, we can use a protractor to measure this angle directly.
10. Using the Options:
11. The options provided are:
    • A. 17°
    • B. 21°
    • C. 25°
    • D. 29°
12. Since the correct answer is given as B (21°), we can infer that the angle measured from the North to the line connecting Adaba to Jata is approximately 21°.

Why Option B is Correct

• Correctness of Option B (21°):
• The bearing of 21° indicates that Jata is located slightly east of the North direction from Adaba. This is a plausible angle for many geographical locations, especially if Jata is situated in a northeast direction relative to Adaba.

Why Other Options are Incorrect

• Option A (17°):
• This angle is too small to represent the direction from Adaba to Jata if we assume Jata is indeed northeast. It would suggest that Jata is almost directly north, which contradicts the given correct answer.
• Option C (25°):
• While this angle is closer to the correct answer, it is still larger than the measured bearing of 21°. This could imply that Jata is positioned more to the east than it actually is.
• Option D (29°):
• This angle is significantly larger than the correct answer. A bearing of 29° would suggest that Jata is further east than what is indicated by the correct answer, which is not accurate.

Common Pitfalls

• Misreading the Compass:
• Students often confuse the direction of bearings, especially if they are not familiar with how to read a compass or a map.
• Assuming Directions:
• It’s important to not assume the direction without proper measurement. Always refer back to the map or coordinate system.

Revision Summary

• Bearings are measured in degrees from North in a clockwise direction.
• The bearing of Jata from Adaba is approximately 21°, indicating a northeast direction.
• Other options (17°, 25°, 29°) are incorrect as they misrepresent the angle from North to Jata.
• Always visualize or plot points on a map to accurately determine bearings.
