I think it might be b. I'm super sorry if I'm wrong I tried my best :(
The biggest common factor number is the GCF number. So the greatest common factor 55 and 65 is 5.
We do not know the length of any of the sides, therefore we can not prove triangle congruence.
Answer:
Step-by-step explanation:
Angle 1 and angle 2 are remote interior angles of angle 6 because angles 1 and 2 are on the inside and it is remote and across from angle six. You can also see this where angle 1 and angle 3 are remote interior angles of angle 5
So in turn angles 2 and 3 are remote interior angles of angle 4 for the same reasoning.
