Full solution stays hidden until you ask for it.
1. Translate directions into perpendicular legs.
2. Use Pythagorean theorem for resultant distance or trig for components.
3. State direction angle relative to the named axis.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Swapping north/east components without regard to reference direction.
