You can put this solution on YOUR website! It appears this is a right triangle.
the formula for a right triangle is:
hypotenuse squared = leg 1 squared + leg 2 squared.
if leg A is the hypotenuse, then the formula would be:
(x-7)^2 + (x+1)^2 = 12^2
If leg B is the hypotenuse, then the formula would be:
12^2 + (x+1)^2 = (x-7)^2
if leg C is the hypotenuse, then the formula would be:
12^2 + (x-7)^2 = (x+1)^2

=============
It would behoove you to provide more information.!
If what @THEO states is true - that this may be a right-angled triangle - his statement that B could be the HYPOTENUSE is
dead-wrong!! Side B = x - 7 is obviously SHORTER than side C = x + 1. So, side B CANNOT be the hypotenuse!!
Also, from what I recall, a right-angled triangle DOES NOT have 3 legs. Instead, it has a HYPOTENUSE (longest side), and
2 legs (one longer than the other or 2 CONGRUENT legs that would make it an ISOSCELES right-angled triangle).
Repost with more information, if help is still needed!
