Do you want to learn how to do it, first?

4. Mimi_x3

Okay|dw:1361360853770:dw|

5. Mimi_x3

Ok, so first we need to find the length of CE Using Pythagorus theorem, are you able to do it?

let me try.

that is a leg, so, a^2+300^2=350^2

?

9. Mimi_x3

|dw:1361361036981:dw|

10. Mimi_x3

Correct, so far.

Okay; let me solve. One moment,

18.278?

13. Mimi_x3

I dont have a calculator with me but if you did sqrt(350^2-300^2), it should be right.

for that, i got 180.27756377319946

15. Mimi_x3

That should be reasonable for the length of that.

Oh. Ok.

17. Mimi_x3

|dw:1361361384973:dw|

Okay.

So you subtract and do not add?

o wait nvm.

k, let me write 180 down.

ok.

Now CN and EA

24. Mimi_x3

now, i dont get how we can find EA; since EN is not given. :/ Let me think.

Ok.

Hmmmm.

I think it is 300.

28. Mimi_x3

how :/

I did $\frac{ 180 }{ x } = \frac{ 300 }{ 500 }$

30. Mimi_x3

similarities?

Proportions,yes; since 180 (ce) is the same side of the triangle as CN.

32. Mimi_x3

|dw:1361361750840:dw| Yeah

You got the same thing too?

ok, let me solve.

I got 300 again.

$\frac{ 350 }{ x } =\frac{ 300 }{ 500 }$

37. Mimi_x3

wait sorry!

the one above yours ^

40. Mimi_x3

does that make sense?

42. Mimi_x3
43. Mimi_x3

So both ways got the right answer. YOu should check your algebra.

Okay. So it was 350/x = 300/500 or x/350=500/300 ?

45. Mimi_x3

yeah!

46. Mimi_x3

same thing.

you just chose to do the large figure first.

Okay. thanks!

49. Mimi_x3

:)

mimi

so i write 583.333333333333 as my answer?

@Mimi_x3

53. Mimi_x3

its whole number thats a decimal form :P

54. Mimi_x3

it says*

oh. right. so 583.

LOL. Thanks!

I have one other math question; mind If I tag you?

58. Mimi_x3

:)

59. Mimi_x3

sure

thanks. just one more!
