The equation that will solve for x is:
112° + 2x + 8° = 180°
Simplifying this equation gives:
2x + 120° = 180°
Subtracting 120° from both sides:
2x = 60°
Dividing by 2:
x = 30°

An illustration shows a slanting line intersecting with two lines that appear parallel. The angles that the slanting line forms with the top line are labeled from the top left in a clockwise direction as 1, 2, 4, and 3. The angles that the slanting line forms with the bottom line are labeled from the top left in a clockwise direction as 5, 6, 8, and 7.
