do you know what mean Pythagorean numbers ?

OpenStudy (anonymous):

no? have no clue?

OpenStudy (anonymous):

Two of the numbers given must add up to the third for it to make a right triangle.

jhonyy9 (jhonyy9):

so for example 3,4 and 5 because 3^2 +4^2 = 5^2 9 + 16 = 25 ok ?

OpenStudy (anonymous):

i dont get it

OpenStudy (anonymous):

i stink at math

OpenStudy (anonymous):

it's C. 18, 24, 30 would you like me to explain?

jhonyy9 (jhonyy9):

OpenStudy (anonymous):

RETARD

OpenStudy (anonymous):

nvm i dont even know

jhonyy9 (jhonyy9):

12^2 +16^2 = 144+256 = 400 the hypothenuse will be sqrt400 =20 cm so is C .
