ok well u need to know the Pythagreon Theorem which is a^2+b^2=c^2
c^2 is always the hypotenuse
so your equation is 10^2=6^2+b^2
100=36+b^2
subtract 36 from both sides
64=b^2
square root each side
8=b so your other leg is 8 cm

Just use the Pythagoream theorem of a^2+b^2=c^2 (a and b being each leg, and c being the hypotenuse.)
6^2+x^2=10^2
36+x^2=100
x^2=64
x=8
The other leg is 8 cm

let the unknown side be x.
then using pythagoras theorem,
x^2 + 6^2 = 10^2
x^2 = 64
x = 8

10^2 - 6^2 = answer^2
100 - 36 = answer^2
64 = answer^2
answer = square root (64)
answer = 8
