Pls help and show how do show it on paper

there is really no way to show but all you have to do is look at the angle across from angle 1 which is angle 4 because it is vertical to angle 1. hope that helps

it 4

Step-by-step explanation:

because both sides are symmetrical and you don't need paper to do it and it's a 90-degree angle so you tell by looking.

hope this helps

answer: 0.1,0.85

step-by-step explanation:

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
