Can someone please help me, I’m struggling

Answer:
Vertical
Step-by-step explanation:
I got this correct :) and also because if it would be supplementray, those angles would be placed different (on one line) had they’re not corresponding or alternating. So its C - vertical. :) Can you please mark me as brainliest?
Answer:
If that says 6 and 8 then they are vertical. If it's 6 and 3 then they are alternate interior. Forgive me for I am blind.
