Final answer:
The bearing of town A from town B is 0°.
Step-by-step explanation:
The bearing of town A from town B can be determined by finding the angle between the due north direction and the line connecting town A and town B. To do this, we can use trigonometry.
- Draw a diagram with town A and town B located in it. Label the distance between them as 40 km.
- Draw a vertical line from town B to represent the due north direction.
- Use trigonometry to find the angle between the line connecting town A and town B and the due north direction. Since the line is due north of town B, the angle would be 0°.
Therefore, the bearing of town A from town B is 0°.
