Question

If the hypotenuse is 41 inches, and one of the legs is 40 inches, what is the length of the other leg in inches?

Answer 1

very much like the last one

Answer 2

start with
\[a^2+40^2=41^2\] then solve for \(a^2\) and then for \(a\)

Answer 3

yeah.. thats the one i was looking at and got mixed up with..

Answer 4

the other leg is 9 inches

Answer 5

or you can go right to
\[a=\sqrt{40^2-41^2}\]

Answer 6

ah that is the one you have before, right?

Answer 7

thanks but i am going the long way.
81?

Answer 8

yes, 81 is \(a^2\)

Answer 9

yeah it is

Answer 10

and so this time \(a=9\)
