42, 63, 75 is the answer
add 63+75 and subtract that answer from 180. that ends up being 42 and then just put in order
It would be at 2. Here is why: -2 and 4 are 6 places away from each other. Now divide that by 3 (for the thirds). so each third is 2. Now thirds 2will be four, so add that to -2 and you get 2.
A. is the correct one I did it on my test and got it right
