you want to use pythagoras' theorem...

3. anonymous

How would I use that?

4. butterflydreamer

do you know the formula? :)

5. anonymous

No, but every time I try and look something like that up; I end up needing it explained anyway. Could you give me how to do it in retard form?

6. butterflydreamer

sureee... So basic pythagoras' rule is |dw:1440764577440:dw|

7. butterflydreamer

so if we're given that the sides are 39in and 52in then we have this triangle: |dw:1440764771740:dw|

sooo what does 39^2 + 52^2 = ?

9. anonymous

What I got was 4225, but that answer is not in any of my multiple choice options for the problem.

10. butterflydreamer

LOL yes, because that's our value for x^2 not "x". see how in the diagram i wrote: "x^2 = 39^2 + 52^2" x^2 = 4225 To find "x", you want to SQUARE ROOT 4225.

Oh ok; see what did I tell you? I'm math retarded lol.

12. butterflydreamer

haha it's okay :)! did you get it?

13. anonymous

Yes I got 65in.

14. butterflydreamer

15. anonymous

16. butterflydreamer
