    wait nope actually you you need angle between 0 to 360 degree and circle add up to 360 degree so subtract 360 ntil u get POSITIVE angle between 0 to 360

    25? I subtracted by 180 that gave me 25. and then subtracted 180-205 it gave me -25. tan25 is a answer choice so do you think that would be it
