Answer:
Corresponding angle theorem, vertical angle theorem, and the transitive property of congruence.
Step-by-step explanation:
Considering a set of parallel lines cut by a transversal. (Refer the attached image).
Now that lines J and K are parallel, then by "corresponding angle theorem"

By "vertical angle theorem"

Using, "transitive property of congruence"

And that is our required proof. In this whole proof we have used "corresponding angle theorem", "vertical angle theorem", and the "transitive property of congruence".

Answer:
b. second answer.
Step-by-step explanation:
I think b.
I replaced the x in x-2 with 2, and the x in x+3 with -3, and got zero on both. 0x0=0
2/0=undefined
