Answer:

The other leg is 12

Step-by-step explanation:

We can use the Pythagorean theorem to solve this problem.

a^2+b^2 = c^2

The legs are a and b and the hypotenuse is c

5^2 +b^2 = 13^2

25 + b^2 = 169

Subtract 25 from each side

25-25 +b^2 = 169-25

b^2 = 144

Take the square root of each side

sqrt(b^2) = sqrt(144)

b= 12
