"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"
