Hi , i suck at these and they’re probably so easy but pls

Your answer would be D) 13.

Step-by-step explanation:

This is really simple. But, I struggled with this as well since middle school. Then I have an amazing math teacher in high school who helped me with this.

12^{2} +5^{2} = 13^{2}

a^{2}+b^{2}=c^{2}

13

Step-by-step explanation:

well you will use something called Pythagorean theorem and its literally

a^2 + b^2 = c^2

and from what i see it'll be 13
