What Is X For Number 14 class=

It's a right triangle.  So

         (x²) + (10²)  =  (7+x)²

         x²  +  100  =  49 + x² + 14x

That may look ugly, but I'm pretty sure you can handle it from this point.

Wow !  I just noticed that you can subtract  x²  from each side
and not even have to mess with it again.
