Where is the point of tangency for (AB) on circle D? on circle E? Rest in comments.

OpenStudy (hlambach):

Help! I don't know what this even means! :/

OpenStudy (hlambach):

@ganeshie8

OpenStudy (hlambach):

yeah, well i don't either... haha

OpenStudy (jim766):

Do you know what tangent means?

OpenStudy (hlambach):

Yep, I know what a tangent line to a circle is.

OpenStudy (hlambach):

Is the answer just B?

OpenStudy (jim766):

So they want to know what point b is I don't think there is enough info to figure it out

OpenStudy (hlambach):

Exactly...

OpenStudy (jim766):

That would be my guess, just b

OpenStudy (hlambach):

oh ok, thanks!

OpenStudy (hlambach):

@Jim766 can you help me again, please? haha, using the same diagram

OpenStudy (hlambach):

How can you use parallel lines to find the measure of <CEA?

OpenStudy (jim766):

Lol

OpenStudy (hlambach):

Wait, never mind, I get it. Its the perpendicular transversal thing

OpenStudy (hlambach):

*perpendiculare tranversal theorem

OpenStudy (hlambach):

i dont need help anymore, but thanks everyone!

OpenStudy (jim766):

Alternate interior angles

OpenStudy (hlambach):

yeah that too

OpenStudy (jim766):

The confusing part is that cant do it with out some more information

OpenStudy (hlambach):

Oh, don't worry, I already have the info, that was part of a proof, so I already know other stuff
