It is the angle where it says "A".
Red + green = 24; (1)
red + blue = 10; (2)
blue + green = 20; (3)
(1) - (2):
green - blue = 14; (4)
(3) + (4):
2 * green = 34;
green = 17;
Simple substitution gives:
blue = 3;
red = 7;
The set builder notation is {-8,-3,4,7} and the number line would begin at -8 and continue to positive 7. It would show a closed dot on top of -8 with a line that continues to a closed dot above 7.
The union of the 2 sets means that the final notation includes all elements.
