Question

medalllllllllll!

Answer 1

find a

Answer 2

You can use the Pythagorean Theorem.

Answer 3

a^2 = b^2 + c^2

where a is hypotenuse, a and b are the length of the other leg

then

41^2 = 40^2 + c^2
c^2 = 41^2 - 40^2
c^2 = 1681 - 1600
c = sqrt (81)
c = 9 inch

Answer 4

get it @terminally_capricous ??

Answer 5

Thank you @freckles and @gerryliyana ! I get it now.

Answer 6

I wish I could medal both of you :/

Answer 7

Well since you already have the answer...
\[40^2+a^2=41^2 \\ a^2=41^2-40^2 \\ a^2=(41-40)(41+40) \text{ by difference of squares } \\ a^2=(1)(81) \\ a^2=81 \\ a=9\]

Answer 8

You can do the problem without a calculator ^ :)
