I'd guess 90. Isn't this vector problem? Any math majors here should be able to help!

Now that you have given the ans, the solution strikes me as very obvious, but unfortunately thats not how GMAT works!

anyway imagine that diaognals of 3 adjacent sides of a cube form an equilateral triangle in a plane! viola!
