Let's start by identify a 30-60-90 triangle
If we compare those two traingles we can stablish the following relation:
Therefore, a=6
u is the opposite side to the 90° angle, therefore
on the other hand, v is the opposite side to the 30° angles, so
There are three dials on a combination lock. Each dial can be set to one of the numbers 1, 2, 3, 4, 5 The three digit number 553

Take the cross product, then normalize the result.
This has norm
and so a unit vector orthogonal to both given vectors is
An equally correct answer would be the negative of this vector, since
