put this solution on YOUR website!Well i think its just simply adding or subtracting to make the question simpler:
Since it goes 90CCW then 30CW it is safe to say that it just goes 60CCW because you are doing one step instead of two. Its like saying: Simplify this pattern. 4 Steps right, 3 Steps left. Instead of going left 4 steps and then BACK 3 steps you can just say take one step right to make it simpler. You would end up in the exact same spot either way.
