Putting the given value of 'x' in the equation:

Answer:

I believe it would be cpctc

Step-by-step explanation:

It would be that due to the fact it is not talking about an angle so therefore it wouldn't be ASA, it also wouldn't be definition of congruent segments because that is represented using segments and as you can see it has no tick marks, which need to be seen for the definition of congruent segments. CPCTC would be correct because it stands for corresponding parts of congruent triangles are congruent and can be represented in both lines and angles, and the problem is asking about lines and how you know they are congruent.
