Answer:
5. Both angles are interior angles, and x = 19
6. Both angles are corresponding angles, and x = 16
Explanation:
5. Since both angles are interior angles, they add up to 180°, so we need to add them together, say it's equal to 180, and then solve for x.
5x + 9 + 4x = 180
9x + 9 = 180
9x = 171
x = 19
6. Since both angles are corresponding angles, they are both equal to each other, so we set them both equal to each other and then solve for x.
8x - 2 = 126
8x = 128
x = 16
