Without additional information or a diagram, it is not possible to answer these questions. Please provide more context or information.

I'm sorry, but I need more information or context to provide the answers to the questions. Please provide any additional details or information about the lines, angles, or diagram mentioned in the questions.

To determine the value of x in each of the given questions, we need to analyze the relationship between the lines mentioned and identify the conditions for them to be parallel or the measures of the specified angles.

11. To find the value of x for line l to be parallel to line m, we need additional information or equations representing the lines.

12. Similarly, we require more information or equations to determine the specific value of x for line l to be parallel to line m.

13. Without additional information or equations, we cannot determine the value of x for line l to be parallel to line m.

14. To find the value of x for line n to be parallel to line m, we need more information or equations that describe these lines.

15. To find the measure of angle m<c, we need to identify the angle in question and any relevant information or relationships within the given figure or problem. Without specific details, it is impossible to provide an exact value.

16. To find the measure of the exterior angle, we require information about the figure or problem, specifically the angle or angles needing measurement. Without more details, we cannot determine the measure.

17. To find the measure of the exterior angle, we need additional information or equations that relate to the given figure or problem. As hinted, finding the value of x first would be necessary before applying it to calculate the exterior angle.

18. Without an accompanying diagram or specific details about the relationships between the variables x, y, and z, it is impossible to provide the values for these variables.
