The answer is 315 degrees!
Bearing 0 degrees would be north
For sailors, bearing is the angle measured clockwise from North. For mathematicians, direction is measured counter-clockwise from the positive x-axis. Thus, due East as a bearing would be 90 degrees, since it is 90 degrees clockwise from North, and East as a direction would be 0 degrees, since East is the same as the positive x-axis. So yeah, there you go.
Usually north when talking about bearings, it is one full rotation from 0o.
An angle of 315 degrees is a reflex angle
The answer is 315 degrees!
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.
The direction NNW plus 90 degrees is ENE. ---------------------- NW is a bearing of 315 and NNW is a bearing of 337.5. Add 90 to this, and subtract 360 because we have "gone round": 337.5 + 90 = 427.5; 427.5 - 360 = 67.5. This is past NE, so the answer is ENE.
45 degrees is NE
On a compass, the direction with a bearing of 450 degrees is located in the northwest region. The standard compass measures the direction in degrees, starting from North at 0 degrees and proceeding clockwise until 360 degrees. Hence, a bearing of 450 degrees is just beyond the West direction, which is marked at 270 degrees, and points towards the northwest. ⓗⓣⓣⓟⓢ :⃝ /⃝ /⃝ⓦⓦⓦ .⃝ⓓⓘⓖⓘⓢⓣⓞⓡⓔ②④ .⃝ⓒⓞⓜ /⃝ⓡⓔⓓⓘⓡ /⃝③②⑤⑥⑤⑧ /⃝Ⓡⓐⓙⓘⓥⓑⓙⓞⓝⓐ /⃝

When we measure wind direction, we go by the direction it is blowing out of. If we have 315. 360-45 = 315 which on a compass is NW. This wind we are talking about here is out of the NW. It would then be blowing SE.
West by Southwest, if you are facing west it would be at your 11 o-clock.
Usually north when talking about bearings, it is one full rotation from 0o.
