If one leg is 12, the second is 3, what is the hypotenuse?
Use the Pythagorean theorem: 12^2+3^2=x^2. Solve and you get x=3 sqrt(17). The hypotenuse is approximately 12.3693.

About Pythagorean Theorem
The Pythagorean Theorem states ''In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).''
