@bohotness Thankyou sooo much! @iGreen I tried. Im still confused. XD
OpenStudy (igreen):
Okay, well C is incorrect.. .-.
OpenStudy (anonymous):
what is it then @iGreen
OpenStudy (igreen):
Try 20, 21, 29.
\(\sf a^2 + b^2 = c^2\)
Plug in what we know:
\(\sf 20^2 + 21^2 = 29^2\)
Simplify.
OpenStudy (igreen):
Simplify 20^2 and 21^2 and add them together. Then simplify 29^2 and see if it is equal to 20^2 + 21^2.
