Did you know that to calculate the bearing of point A from point C, we can use a combination of trigonometry and vector addition? In the given scenario, the plane initially travels 340km towards port B on a bearing of 23 degrees North East from port A. Then, it changes its direction to North West on a bearing of 60 degrees for 680km to reach port C. To find the bearing of point A from point C, we can imagine a vector from point C to point A and use vectors from point C to point B and from point B to point A. By adding these two vectors together, we can determine the resultant vector which represents the direction from point C to point A. The bearing of point A from point C can then be calculated using trigonometry based on the components of the resultant vector. This application of vectors and trigonometry enables us to mathematically determine the bearing between two locations in a real-world scenario.
