**Riding the Train --Vecotrs & components**

A passenger train is cruising directly to the north at 16.0 mi/hr.

what are the speed and (numerical) direction of a passenger with respect to the ground on this train, if he now walks east-ward at 5.4 mi/hr?

---Compass heading in degrees: N=0, E=90, S=180, and W=270

I know i have to add velocities add as vectors.

Work-

i drew a triagle, the y commponent being 16 and the x (hoizontal) component being 5.4 and i ahve to ifnd the resultant speed. aka: the hypothenuse of the triangle.

But i don't know how to do that when i don't have an angle.

Please help
