2. timo86m

same as before :P

4. timo86m

100/(100+150)=240/x correct :D

Thanks!

let me solve.

7. timo86m

ok

Would $\frac{ 100 }{ 240 } = \frac{ 150 }{ x }$

work?

10. timo86m

100/250 :P

oh. 100/250= 240/x?

12. timo86m

250 not 240

13. timo86m

yup yup

240 is the base of the smaller triangle.

So,yes?

16. timo86m

240 is base of small triangle indeed

17. timo86m

and its given leg is 100

Did I set it up right, then?

Oh.

20. timo86m

however the long leg of the big triangle is 150+100=250 and its base is x

21. timo86m

so knowing the proportions small leg over big leg= small base/ big base

okay.

How would you set it up.

24. timo86m

100/(100+150)=240/x is 100/250=240/x

Oh.

26. timo86m

small leg over big leg= small base/ big base

Let me write that down,then.

28. timo86m

ooh good idea

Yeah. One second.

625 m is what I got.

Is that correct?

32. timo86m

i got 600 lol

Wha... I used a calculator, and you?

I did it wrong. Yes.

1/250?

36. timo86m

(100/250) = 240/x (100/250) *(240/1)= 240/x *(240/1) multiply 240 over 1 to get 1/600=1/x Just flip both sides 600=x

Hm...okay.

38. timo86m

or copy paste (100/250) = 240/x into wolframalpha.com

okay.
