Answer:
12 cm 
Step-by-step explanation:
The Pythagorean Theorem is as follows: 

A and B represent the side lengths (legs) and C represents the hypotenuse. 
The length of one leg equals 5cm. (This can be represented by either a or b) 
The hypotenuse equals 13 cm. 
Plug these into the equation from above: 

Solve for the other leg: 
     Square what's in the parentheses from above
                          Square what's in the parentheses from above
 Subtract 25 from 169
                                  Subtract 25 from 169 
 Square root both sides
                            Square root both sides 
a = 12 cm                         
Thus, the length of the other leg is 12 cm. 
Let's check our answer: 
 Square everything
                        Square everything
144 + 25 = 169                      Add
169 = 169 
Because both sides are equal it means that 12 cm is the correct answer. 
Hope this helps!!
