On this problem i don’t know how to do it and i’m getting tired of doing this

If it's Pythagorean Theorem, then use the following:

You have to multiply the 2 values by themselves if you are trying to find the Hypotenuse, then you need to add those together, and then find the square root.

10 x 10 = 100

15 x 15 = 225

100 + 225 = 325.

here's a poem i finished a while ago. i hope you like it and that it inspires you.
