Since -268° is a negative angle it is measured clockwise from the right
side of the x axis and is indicated by the green curved arrow above.
Now I will draw a positive angle which is coterminal with that -268° angle.
But it is measured clockwise with the red curved arrow below:
And that red curved arrow measured counter-clockwise from the right
side of the x-axis is found by subtracting the absolute value of the
green angle or 268° from 360° and that gives 360°-268° or 92°.
So that's the answer 92°
