Please help! It’s for a test, I’ll also give brainliest! Thank you
i think it is 18
step-by-step explanation:
second option
step-by-step explanation:
the measures of a triangle equal 180. use that to find x.
2x+3x+4x=180
9x=180
9x/9=180/9
x=20
now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.
because angle a is 40°, the first option doesn't work.
because angle b is 60°, the second option does work.
when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.
when you add angle a and c, you get 120°, which is not 100.
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
