Which special version of the pythagorean theorem can you use to find the length of any squares diagonal, d, using only the length of its side, 12 inches. will give 30 points to whoever can me

The square's diagonal is the triangle's hypotenuse.

The Pythagorean theorem is =

Here, 'c' is the hypotenuse and 'a' and 'b' are the two sides of the triangle.

As the side is given 12 inches, so this becomes

inches

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
