An ocean liner heading west at 25 km/hr comes into a current of 15.0 km/hr directed 30 degrees north of east. Find the new velocity of the liner.
----------------
Heading west is 270 degs
30 degrees north of east is 060 degs
-----
Makes a triangle with sides of 25 and 15 with an included angle of 30 degs.
The resultant speed is the 3rd side of the triangle.
---
Draw the 25 side originating at the Origin.
The resultant heading is 270 degs + the angle at the Origin.
==================
PS Boats don't use km/hr, the use knots for speed.
