Okay|dw:1361360853770:dw|
Mimi_x3
  • Mimi_x3
Ok, so first we need to find the length of CE Using Pythagorus theorem, are you able to do it?
anonymous
  • anonymous
let me try.
anonymous
  • anonymous
that is a leg, so, a^2+300^2=350^2
anonymous
  • anonymous
?
Mimi_x3
  • Mimi_x3
|dw:1361361036981:dw|
Mimi_x3
  • Mimi_x3
Correct, so far.
anonymous
  • anonymous
Okay; let me solve. One moment,
anonymous
  • anonymous
18.278?
Mimi_x3
  • Mimi_x3
I dont have a calculator with me but if you did sqrt(350^2-300^2), it should be right.
anonymous
  • anonymous
for that, i got 180.27756377319946
Mimi_x3
  • Mimi_x3
That should be reasonable for the length of that.
anonymous
  • anonymous
Oh. Ok.
Mimi_x3
  • Mimi_x3
|dw:1361361384973:dw|
anonymous
  • anonymous
Okay.
anonymous
  • anonymous
So you subtract and do not add?
anonymous
  • anonymous
o wait nvm.
anonymous
  • anonymous
k, let me write 180 down.
anonymous
  • anonymous
ok.
anonymous
  • anonymous
Now CN and EA
Mimi_x3
  • Mimi_x3
now, i dont get how we can find EA; since EN is not given. :/ Let me think.
anonymous
  • anonymous
Ok.
anonymous
  • anonymous
Hmmmm.
anonymous
  • anonymous
I think it is 300.
Mimi_x3
  • Mimi_x3
how :/
anonymous
  • anonymous
I did \[\frac{ 180 }{ x } = \frac{ 300 }{ 500 }\]
Mimi_x3
  • Mimi_x3
similarities?
anonymous
  • anonymous
Proportions,yes; since 180 (ce) is the same side of the triangle as CN.
Mimi_x3
  • Mimi_x3
|dw:1361361750840:dw| Yeah
anonymous
  • anonymous
You got the same thing too?
anonymous
  • anonymous
ok, let me solve.
anonymous
  • anonymous
I got 300 again.
anonymous
  • anonymous
\[\frac{ 350 }{ x } =\frac{ 300 }{ 500 }\]
Mimi_x3
  • Mimi_x3
wait sorry!
anonymous
  • anonymous
What about my other reply?
anonymous
  • anonymous
the one above yours ^
Mimi_x3
  • Mimi_x3
your one: http://www.wolframalpha.com/input/?i=%28350%29%2F%28x%29%3D%28300%29%2F%28500%29
anonymous
  • anonymous
does that make sense?
Mimi_x3
  • Mimi_x3
my one: http://www.wolframalpha.com/input/?i=x%2F350%3D500%2F300
Mimi_x3
  • Mimi_x3
So both ways got the right answer. YOu should check your algebra.
anonymous
  • anonymous
Okay. So it was 350/x = 300/500 or x/350=500/300 ?
Mimi_x3
  • Mimi_x3
yeah!
Mimi_x3
  • Mimi_x3
same thing.
anonymous
  • anonymous
you just chose to do the large figure first.
anonymous
  • anonymous
Okay. thanks!
Mimi_x3
  • Mimi_x3
:)
anonymous
  • anonymous
mimi
anonymous
  • anonymous
so i write 583.333333333333 as my answer?
anonymous
  • anonymous
@Mimi_x3
Mimi_x3
  • Mimi_x3
its whole number thats a decimal form :P
Mimi_x3
  • Mimi_x3
it says*
anonymous
  • anonymous
oh. right. so 583.
anonymous
  • anonymous
LOL. Thanks!
anonymous
  • anonymous
I have one other math question; mind If I tag you?
Mimi_x3
  • Mimi_x3
:)
Mimi_x3
  • Mimi_x3
sure
anonymous
  • anonymous
thanks. just one more!
anonymous
  • anonymous
let me post it.
