Bearing is a direction. The bearings are typically based upon the ship's navigational gyroscope, though if the gyros are not working, the magnetic compass can be used. The ship's course is given as a bearing that is to be steered. Contact information is based on a bearing from the ship. By tracking the bearing of a contact and the range, you can determine the contact's course and speed. Something that is at a 'Constant Bearing' is going to be very close, if not hit, the ship. "CBDR" was something you hated to hear, Constant Bearing Decreasing Range meant that you were going to have to work out course and speed and make recommendations to the Captain as to how to avoid based on Rules of the Road, etc.
Ancient ship Praise of the Two Lands is the first ship bearing a name built by Egyptian pharaoh Sneferu.
The ship is traveling west which means that the ship is traveling at a bearing of 270 degrees. The lighthouse is 10km northwest of the ship at time point 0. Northwest means the lighthouse is at a bearing of 315 degrees from the ship. This means that the angle between the direction the ship is going and the lighthouse is 315 - 270 = 45 degrees.

plot the ships position
We will assume that the curvature of the Earth is not taken into account for this. Approx heading = 283 degrees & Distance = 250 km from port.Draw a rough sketch with questions like these and in fact the course taken by the ship works out as a right angle triangle.

The compass bearing indicates the direction in which an object or location is located relative to the position of the observer. It is measured in degrees, with 0 degrees representing north, 90 degrees representing east, 180 degrees representing south, and 270 degrees representing west on a standard compass.
