Answer 2

Answer:

x = 25

The lengths form a pythagorean triple

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

Explanation:

Use the pythagorean theorem to get the following

$a^2 + b^2 = c^2\\\\c = \sqrt{a^2 + b^2}\\\\\text{x} = \sqrt{15^2 + 20^2}\\\\\text{x} = \sqrt{225 + 400}\\\\\text{x} = \sqrt{625}\\\\\text{x} = 25$

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".
