It is asking me to find m and n. I have the answer for it but not all the steps for it. The answer should m=60 and n=12
I think this is what I need to do 6m-120, but right after that I get confused, like how am I supposed to find m and n, would it be 6m-120=180
Keeping in mind that the angle of a straight line always equals 180 so i'm a little confused. Is the m-120 for just that one angle? Or for both?
|did you look at that one site I showed you previously on your previous post? the two angles with 2m and 4m-120 has measurements are congruent since they are corresponding angles
which means 2m=4m-120
Yes I did, but it only talked about supplementary angles. oh okay, wait so 2m=4m-120
it also talked about congruent angles
and it talked about three kinds of congruent angles
the angles I mentioned earlier were corresponding angles
now |dw:1443728005251:dw| the sum of these circled angles is 180 deg
Oh okay, so I got 60. But now to get 5n, aren't vertical angles equal to 180, so 5n+4m=120 ? So 5n+ 4(60)-120=180
vertical angles equal 180
so you got m is 60 right?
replace m with 60 then 4(60)-120+5n=180 and now solve for n
Yes. So n=12
right since you have 240-120+5n=180 120+5n=180 5n=60 n=12 great
Thank you very much for your help!
np on that site they mentioned all the angles that are congruent when you have some picture like this: |dw:1443728172278:dw|
congruent means they have the same degree measurement
hey also one more important thing
yes? Sorry I was looking at other things in that one site you gave me
I confused myself earlier
and I guess I forgot what vertical angles were
but vertical angles are the same not supplementary
Yeah sorry I got confused, but yes.
so hmm... this means n will be different
\[2m=4m-120 \\ -2m=-120 \\ m=60 \\ 4m-120=5n \\ 4(60)-120=5n \\ 240-120=5n \\ 120=5n \\ n=24\]
well it wouldn't be because they are still the same, I just said that it would be 180 but what I meant is that vertical angles are the same :)
but you said n is 12... right? so let me ask ... |dw:1443728686588:dw|
