    Answer:

      ∠1 = 67°; ∠2 = 113°

    Step-by-step explanation:

    Given:

      ∠1 = 2x-3

      ∠2 = 3x +8

      ∠1 +∠2 = 180

    Find:

      ∠1, ∠2

    Solution:

    Substituting the first two relations into the third, we have …

      (2x -3) +(3x +8) = 180

      5x +5 = 180 . . . eliminate parentheses

      x + 1 = 36 . . . . . divide by 5

      x = 35

    Then the angles are …

      ∠1 = 2x-3 = 2(35) -3

      ∠1 = 67°

      ∠2 = 3x +8 = 3(35) +8

      ∠2 = 113°
