Answer 2

you can check each by stating

6^2+8^2=12^8 true or false?
3^2+5^2=6^2 true or false?
15^2+9^2=17^2 true or false?
5^2+12^2=13^2 true or false?


the one that is true is going to be the answer.

Answer 3

I'm confused ( i have never been so good with these )

Answer 4

you don't have to be so good at those,
let me explain what I did, Pythagorean triple means

Answer 5

B
I*
I * side c
I *
side a I *
I *
I______________________*_
C A
side b


the formula of how all sides are proportional if you will,
a^2+b^2=c^2

Answer 6

like
if side a was 3 and side b was 4,
to find c, you would

a^2+b^2=c^2
3^2+4^2=c62
9+16=c^2
25=c^2
c=5 or -5 a distance of a side can't be negative, so it would be just (positive) 5.

Answer 7

ok
thanks!
