Hi, 

the two shorter sides of a right triangle are 8cm and 10cm, 

What is the length of the longest side +highlight_green%28x%29 ?

applying the Pythagorean Theorem

8^2 + 10^2=  x^2

   x^2 = 100+64 

  x^2 = 164

   x =+sqrt%28164%29+=+sqrt%284%2A41%29+=+2sqrt%2841%29     (Tossing out the negative solution for unit measure)
