Trying to get the formula for an angle that is it's direct opposite. I can get it just fine from angles 0 to 180 by adding subtracting 360 from it but from 181 to 360, thats a different story.
Ok let's say I'm trying to get the opposite side for 300 which is 120. I been racking my brains on this for hours.
Any help from math wiz's will be appreciated!
