Question

The numbers 20, 21, 29. form a Pythagorean triple. Which other set of numbers is a Pythagorean triple?

21, 22, 30

40, 42, 58

60, 66, 87

70, 84, 116

Answer 1

3 numbers\(a,b,c\) will be a pythagorean triple if it satisfies the equation \(a^2+b^2=c^2\), where \(c\) is the largest number out of the 3 numbers

Answer 2

@kirbykirby: That's correct.

Answer 3

So it's really just a matter of testing all of your options, and seeing if that equation is true! :)

Answer 4

so which one is it?

Answer 5

Well just test them out... for example, the first one... you just try 21^2 + 22^2, and verify if it's equal to 30^2

Answer 6

\(21^2+22^2=925\), now just verify if 925 is equal to \(30^2\)... if it's not equal, then those numbers are not a Pyhagorean triple

Answer 7

im not very good at this. too bad no one ever gives the answer -.- :(

Answer 8

Because we want you to understand the problem. If we just give the answer, you will not know how to do them on a test :(

Answer 9

in school they only teach us what we need in test, not in real life. i dont think i need math to be a dog sitter lol

Answer 10

at least not complicated math

Answer 11

Well you should know basic math for that. And rally all you are doing here is inputting numbers into a calculator... which could be something you do as a dog sitter when calculating your pay

Answer 12

ok then

Answer 13

I don't want to come off as being mean :( But you should put a bit of effort into finding the solution rather than wait for people to give it to you. If you are struggling, then we can give you more assistance

Answer 14

i just never even learnd this before. i dont want to learn it :(
