1. **State the problem:** We need to find the bearing of point B from point A using the given semicircle protractor. 2. **Understanding bearings:** Bearings are measured clockwise from the North line (0° or 360°) around the point. 3. **Given information:** The protractor is vertical with North pointing straight up from A. 4. **Observation:** The line from A to B passes through the 340° mark on the protractor, extending leftwards. 5. **Calculate the bearing:** Bearings are measured clockwise from North. Since the line is at 340°, the bearing of B from A is simply 340°. 6. **Final answer:** The bearing of B from A is **340°**.
