Planes Velocity Problem

[shizupple]

1. The problem statement, all variables and given/known data

Kyle is flying a plane due north at 230 km/h as a wind carries it due east at 56 km/h. Find the magnitude and direction of the plane's resultant velocity analytically.
236.7 km/h (magnitude)
° (direction)


2. Relevant equations

Tan=opp/adj


3. The attempt at a solution

This should be straightfoward but i guess not?
I tried:
tan^-1 (56/230)=13.7 degrees

Cant seem to figure out why this isnt working it should be straightfoward

I don't see anything wrong. Why do you think it isn't working?

My webassign is marking it wrong... i dont see how it is wrong though??!!

Nevermind I got it they wanted the angle from the other side (76.3). Thanks!
