Which set of side lengths is from a right triangle?

4, 8, 10
9, 10, 15
6, 9, 14
21, 28, 35

Answer 1

\(a^2+b^2 > c^2\) acute
\(a^2+b^2 < c^2\) obtuse
\(a^2+b^2 = c^2\) right

Answer 2

where c is the longest side and a, b are the legs

Answer 3

wat @bibby

Answer 4

for example, let's check it 4,8,10 is right
\(4^2+8^2=16+64=80\)
10 is the hypotenuse. \(10^2=100\) so as we can see \(a^2+b^2<c^2\) and so it isn't right

Answer 5

So A isn't the answer

Answer 6

yeah. I have a good feeling about 21, 28, 35. test it out

Answer 7

\[21^{2}+28^{2}=441+784=1225 35^{2}=\]

Answer 8

that came out wrong, one sec

Answer 9

21^2 + 28^2 = 441 + 784 = 1225 and 35^2 = 1225

Answer 10

so it would seem that \(a^2+b^2=c^2\). there she is

Answer 11

So it's D c:

Answer 12

yeah, you can test t he other 2 to make sure if you'd like

Answer 13

I have a lot to get done tonight, I trust that it's D xD thank you!

Answer 14

any time :)
