Answer:

  • x = [10, 13]

Step-by-step explanation:

  • ∠1 is at least 100° and at most 127° - given

a and b are parallel lines and cut by a transversal.

  • ∠1 and 9x + 10 are alternate interior angles and are therefore congruent.

From  the two statements above we get following inequality:

  • 100 ≤  ∠1  ≤ 127
  • 100 ≤ 9x + 10 ≤ 127
  • 90 ≤ 9x ≤ 117
  • 10 ≤ x ≤ 13
  • x = [10, 13]
