The given angle and angle x are supplementary. This means that when added together they add to 180. So, to solve you can set up an algebraic equation like 180=x+30. Then, subtract 30 from both sides to get 150=x.
X = smallest; x + 2 = middle, and x + 4 = largest x + 2(x+2) = 20 + x + 4 x + 2x + 4=24 +x 3x + 4 = 24 + x 2x = 20 x = 10 so the three integers are 10, 12, and 14
