Answer 1

Hey
I need go soon

Answer 2

But i will help you as much as possible

Answer 3

A^2 + B^2 = C^2
you know this rule right??

Answer 4

So if you just do.. 40^2 + b^2 = 41^2

Answer 5

you end up with 1600 + b^2 = 1681

Answer 6

Subtract 1600 on both side and end up with B^2 = 81

Answer 7

which does make sense in this case because triangle inequality rule says " for any triangle, two sides added must be larger than the hypotenuse"

Answer 8

40 + 9 = 49 and 49 is greater than 41. so it makes it a triangle. It is just a nice way to check if your triangle makes sense :). Leave me a pm if you have a question. I come back in 4 hours.
