## ashley_fay 2 years ago what is the length of side x? if necessary round to two decimal places

1. ashley_fay

2. noseboy908

use the pythorgam therom

3. noseboy908

a^2 +b^2 =c^2

4. noseboy908

where A & B are the 2 shortest sides

5. ashley_fay

after u find the value of c^2 do u find the square root?

6. noseboy908

show me the steps you took

7. Candy13106

8. ashley_fay

19^2+12^2=505

10. ashley_fay

nice hand writing :p

11. noseboy908

no

12. noseboy908

you are given A & C! not B!

13. Candy13106

thank a lotttttttttttttt:)

14. noseboy908

so it's 12^2 + x^2= 19^2

15. ashley_fay

ohh ok i see

16. noseboy908

I mean, the previously given answer is obviously wrong, because the hypotenuse is the longest side so how could the missing side be 505?

17. Candy13106

no its 114

18. ashley_fay

it can't be 505

19. ashley_fay

then how could it be 114??

20. Candy13106

cause u do 12 times 19 then divide by 2

21. noseboy908

no! what is 12^2?

22. Candy13106

u are so wrong

23. noseboy908

\[12^2+x^2=19^2\]

24. Candy13106

still wrong

25. noseboy908

first solve for 12 squared and 19 squared. solve for x from here.

26. ashley_fay

u guys are confusing me

27. Candy13106

i am telling u the right answer is 114

28. ashley_fay

ima go with noseboy cause he makes more sense

29. noseboy908

Imma make a drawing, hold on

30. Candy13106

31. noseboy908

\[12^2+ x^2=19^2\]

32. noseboy908

\[144+x^2=361\]

33. noseboy908

\[x^2=217\]

34. noseboy908

x=?

35. Candy13106

hes still wrong im older go on ask.com if u dont beliveme

36. noseboy908

THEN PROVE IT

37. noseboy908

38. Candy13106

check

39. ashley_fay

-_- u say 114 right

41. ashley_fay

what do u say nose?

42. noseboy908

why are you multiplying 12 x 19?

43. Candy13106

it is on the triangle

44. noseboy908

you first must square it. you never multiply them together

45. Candy13106

thats called counthing, baby

46. noseboy908

http://www.mathsisfun.com/pythagoras.html look at the second example

47. Candy13106
