ok i have this math problem..and i cant work with it maybe one of you can help i have a scan of it soo i need to find the length of line BC, the measuremnet of angle EAC,, arc FE, and angle, C what ive found out is AE and Db are parrell, and trinagle cbd, and cea are similar... just divde 4 by 3 to get the ratio..please help i need to pass this calass.. none of this stuff was in the book..and he wont help..he just says figure it out....and no one in ym class can do it..so please help..oh and this for perople wh have taken or are in geometry...

I think it's isosoceles, er, or however you spell it, if that helps. I'll work on it more after I get Jones soda
Edit: No. God, I forgot everything from Geometry.

It's a right triangle (because the line is tangent to the circle) and, I have a feeling you're gonna have to use sine, cosine or tangent

The answer is 6. Or 452.

tdoc210 · 06-10-2006, 04:20 PM

^ ermm ok... umm swim its a tangent sorry i fogot to add that

tdoc210 · 06-10-2006, 04:22 PM

i think bc might be 11

swim · 06-10-2006, 04:25 PM

Why?
If you explain I might remember stuff.
Edit: I think BC= 21

4/(7+x)= 3/x

The radi are 3 and 4 so that's where I got 7 from. X is BC.

4x=3x+21
x=21

tdoc210 · 06-10-2006, 04:33 PM

well obvioulsey ab= 7 +fa which is 4 is 11, and that looks as though its = to Bc

You can't judge some thing just because it looks as though its equal.

swim · 06-10-2006, 04:39 PM

Look at the proportion I did and ask questions I you have any. You have to use trig to find the angles. And I forgot that part of geometry.
