To determine the value of \( x \) that makes lines \( m \) and \( n \) parallel, we need information about the angles formed by the transversals intersecting the lines. However, since no specific angle measures are provided in your question, I will generalize how to answer it based on the provided responses.
If you analyze the relationships between the angles:
- Alternate Interior Angles Theorem states that if two lines are cut by a transversal and the alternate interior angles are equal, the lines are parallel.
- Consecutive Interior Angles Theorem states that if two lines are cut by a transversal and the consecutive interior angles are supplementary (sum to 180 degrees), the lines are parallel.
Given your options, if you identify that a particular value of \( x \) results in angle relationships that satisfy either of those conditions, you would be able to conclude that the lines are parallel.
Based on the responses provided:
- If \( x = 5 \) or \( x = 10 \) leads to satisfying the conditions of one of these theorems, you would select that response.
Specifically, if the conclusion is from alternate interior angles, you would state:
- "If \( x = 5 \), then \( m \parallel n \) by the Alternate Interior Angles Converse Theorem" or "If \( x = 10 \), then \( m \parallel n \) by the Alternate Interior Angles Converse Theorem", depending on which value satisfies the condition.
Alternatively, if the necessary condition is from consecutive interior angles, then the statements regarding the consecutive interior angles converse theorem would be appropriate.
In summary, the exact value \( x \) depends on the angle measures provided in context, and you would choose the theorem that corresponds correctly to the relationships established by those measures. If you have actual angle measures available, I can assist you in determining \( x \).
