I don’t get this I need a answer

25

Step-by-step explanation:

a^2 + b^2 = c^2

Here, c is the hypotenuse. We'll plug the given numbers into the equation, so we get:

15^2 + 20^2 = c^2

225 + 400 = c^2

625 = c^2

To undo a squared number, you find the square root of it:

= 25

Your answer is 25! If you need more help, just ask :D
