Well the pythagorean theorem states that a^2 + b^2= h^2, where a nd b are the different legs of the triangle and h is the hypotenuse. so:
5^2+b^2=13^2
25 + b^2=169
b^2=169-25
b^2=144
b=12
Also 5,12, 13 is one of the Pythagorean triples.

It's the square root of 13 squared minus 5 squared. So its 169 minus 25 = 144. The sq. root of 144 is 12, and that's the length of the other side.

Use pythagorean theorem & algebra
*Pythagorean*
a= side one b=side 2 c=hypotenuse
a squared + b squared = c squared
5 squared + b squared= 13 squared
25+ b squared=169
b squared=144
b= 12

a^2 +b^2=c^2
5^2+b^2=13^2
25+b^2=169
25-25+b^2=169-25
b^2=144
b= sqrt 144
b=12
5^2+12^2=13^2
25+144=169

use the formula a squared x b squared = c squared. this is the pathagoean theorem. 13 is c because it is the longest side. 5 can be a or b. lets say its a. solve for b.
