use Pythagorean theorem:

c%5E2=a%5E2%2Bb%5E2 than a%5E2=c%5E2-b%5E2
if leg b=12 and hypotenuse c=13 will be:
a%5E2=13%5E2-12%5E2
a%5E2=169-144
a%5E2=25
a=sqrt%2825%29
a=5

Lengths of the sides of this triangle form a 5-12-13 Pythag triple, so missing leg = highlight_green%28matrix%281%2C2%2C+5%2C+units%29%29

That's all....nothing complex!
