Now plot the bearings one by one on the Nautical chart.
First the bearing from -lighthouse A:
Place the parallel ruler on the compass rose at the 045° degree line and transfer that line, passing from lighthouse A and crossing the course line.
Then, the bearing from lighthouse B:
Place the parallel ruler on the compass rose on the 090° degree line and transfer that line passing from lighthouse B and crossing the course line.
Thirdly, the bearing from Island C:
Place the parallel ruler on the compass rose on the 135° degree line and transfer that line passing from Island C and crossing the course line.
Generally, when using three LOPs and due to small errors in the bearings, a triangle may form where they intercept.
In this case the center of the triangle will be the fix position.
