Answer:I think the answer is
1. x=8
Step-by-step explanation:
1. X=8
2. X=1⅓
3. 0x=-12
4. -8x=0
5. 0x=24
Use the Pythagorean theorem:

c - a hypotenuse
a, b - legs
We have: a = 9 and c = 12. Substitute:

<em>subtract 81 from both sides</em>

A Pythagorean triple consists of three positive integers a, b and c, such that
.
is not positive integer.
<h3>The sides of the triangle do not form a pythagorean triple.</h3>
