Answer:

A) 12

Explanation:

We are gonna use the the formula for the Pythagorean Theorem

a^2 + b^2 = c^2

so that will be 5^2 + b^2 = 13^2

so now that we have the equation we just solve it

5^2 + b^2 = 13^2

25 + b^2 = 169

b^2 = 144

b = 12

Check:

5^2 + 12^2 = 13^2

25 + 144 = 169

so the answer is A) 12
