Here's how to solve this navigation problem:
Part a) Represent the information in a diagram.
Let P be the starting port, Q be the intermediate port, and R be the final port.
- From P to Q: The ship sails on a bearing of N45°E for 15 km. This means 45° clockwise from the North direction at P.
- From Q to R: The ship sails on a bearing of S45°E for 20 km. This means 45° clockwise from the South direction at Q.
Let's analyze the angle at Q.
- Draw a North line at P and a North line at Q. These lines are parallel.
- The angle between
