It might be C. Not sure.
OpenStudy (anonymous):
How did you get that answer?
OpenStudy (anonymous):
\[
\frac{35\pi}{126} = \frac{x}{360}
\]
OpenStudy (anonymous):
Pi gets canceled out right?

No
OpenStudy (anonymous):
Oh, then idk how to do it. Do I cross multiply?
OpenStudy (anonymous):
You need to isolate \(x\).
OpenStudy (anonymous):
How do I do that?
OpenStudy (anonymous):
You can cross multiply

Okay, give me a minute.
OpenStudy (anonymous):
All you really have to do is multiply by \(360\).
OpenStudy (anonymous):
Yeah, I have \[\frac{ 126x }{ 12,600 } \] right now.
OpenStudy (anonymous):
no

\[
x = 360\times \frac{35\pi}{126}
\]
OpenStudy (anonymous):
\[\frac{ 35\pi }{ 12,600 } ??\]
OpenStudy (anonymous):
\[
x = 360\times \frac{35\pi}{126} = \frac{ 360\times35\pi}{126}
\]
OpenStudy (anonymous):
You haven't learned fractions yet either?
OpenStudy (anonymous):
I have, but I do independent studies so I have no one to physically explain this to me. Sorry.
