x = 80
the sum of the angles round a point is 360°
the 3 angles here must sum to 360°
3x + x - 27 + 67 = 360
4x + 40 = 360
subtract 40 from both sides.
4x = 360 - 40 = 320
divide both sides by 4
x =
= 80
thus the 3 angles are 67°, 240° and 53°

-3+3 because it is equal to zero, and zero is not positive nor negative. All absolute values are positive unless the number is zero.
