The line segment is rotated 180 degrees counterclockwise about the origin to form E'F'. Which statement describes EF? (4 points) E'F' is perpendicular to EF.
Ob
E'F' and EF are equal in length.
Od
E'F' is half the length of EF.
E'F' is greater than twice the length of EF.
Od

47 - 90 = 43

43 - 180 = x

x = 137

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
