I need help. will fan and medal.

Here is the question. @Luigi0210 @iambatman

OpenStudy (luigi0210):

If they're parallel, that means the angels have the same degrees. So <1 will be the same as <5 right?

OpenStudy (r_josh10):

So is it 140 degrees?

OpenStudy (luigi0210):

Yes, <5 will be 140. Now we're looking for <7. <5 and <7 will add up to 180. So 140+x=180. Think you got it?

OpenStudy (r_josh10):

soo the answer is.... ? 40=x

OpenStudy (luigi0210):

Yup~

OpenStudy (r_josh10):

So 40 equals 7

OpenStudy (luigi0210):

Correctt

OpenStudy (r_josh10):

OK THANKS!!

OpenStudy (r_josh10):

What about this one? @Luigi0210

OpenStudy (luigi0210):

It would be the same as the last, same properties.

OpenStudy (r_josh10):

C??

OpenStudy (r_josh10):

@Luigi0210

OpenStudy (luigi0210):

129+61 gives you what?

OpenStudy (r_josh10):

190

OpenStudy (luigi0210):

Right, when you cut a line by a parallel line, you get 4 sections. Each 90, two of them adding to 180. So that's 10 degrees more.

OpenStudy (r_josh10):

190

OpenStudy (luigi0210):

It's suppose to be 180, not 180 :P

OpenStudy (r_josh10):

So which is the answer?

OpenStudy (luigi0210):

*180 not 190 -.- Sorry about that

OpenStudy (r_josh10):

Soo the answer is B.)61?

OpenStudy (r_josh10):

@Luigi0210

OpenStudy (luigi0210):

Nope, it would be A.. 51+129=180

OpenStudy (r_josh10):

ohh ok thanks!
