Answer 2

x = 25

The lengths form a pythagorean triple

=========================================================

Step-by-step explanation:

Use the pythagorean theorem to get the following

`a^2 + b^2 = c^2\\\\c = √(a^2 + b^2)\\\\\text{x} = √(15^2 + 20^2)\\\\\text{x} = √(225 + 400)\\\\\text{x} = √(625)\\\\\text{x} = 25\\\\`

Since we end up with a whole number, we do form a pythagorean triple of 15,20,25 or you can write it as 15-20-25

A pythagorean triple is where a,b,c are all integers that satisfy the pythagorean theorem above.

This is not a primitive pythagorean triple because we could divide all three values by the GCF 3 to get the triple 3-4-5. The keyword for this paragraph is "primitive".
