  1. "90 miles south and 20 miles east of port"
    means the direction along which the ship must sail is:
    x=-90, y=20
    angle = atan(20,-90) = 180° - 12°-31'-44"
    = 167°-28'-16" (in trigonometry notation).

    To convert trigonometry notation to bearing, subtract angle from 90° or 450° if the angle exceeds 90°.

    Bearing (clockwise from north)
    = 450° - 167°-28'-46"
    = 282°-31'-44"
