Find the length of the unknown side of the right triangle with legs a and b and hypotenuse c.
a=5
c=13
---
b = sqrt[c^2-a^2] = sqrt[169-25] = sqrt(144) = 12

given:
a=5
c=13
to find:
b
use Pythagorean theorem:
c%5E2=a%5E2%2Bb%5E2
b%5E2=c%5E2-a%5E2
b%5E2=13%5E2-5%5E2
b%5E2=169-25
b%5E2=144
b=sqrt%28144%29
b=12
