Hi,
the two longer sides of a right triangle are 8cm and 10cm, 
What is the length of the shorter side {{{ highlight_green(x)}}} ?
applying the Pythagorean Theorem
x^2 + 8^2 = 10^2
   x^2 = 100-64 = 36
  x^2 = 36
   x = 6cm     (Tossing out the negative solution for unit measure)
CHECKING our answer***
{{{ (6m)^2 + (8cm)^2 =  36m^2 + 64cm^2 = 100cm^2 = (10cm)^2}}}
Wish You the Best in your Studies.
