Answer:
A) 12
Step-by-step 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
