Answer:
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]
