Explanation:

come on, now, this is one of the (if not THE) most important formula you need to remember for the rest of your life :

a² + b² = c²

with c being the Hypotenuse (the side opposite of the 90° angle), a and b are the legs.

so, in our case, we have then

x² = 5² + 12² = 25 + 144 = 169

x = sqrt(169) = 13
