what is x for number 14.
x^2\((x+7)^2=x^2+10^2 x^2+14x+49=x^2+100 14x+49=100 14x=51 x=3.64\)
It's a right triangle. So (x²) + (10²) = (7+x)² x² + 100 = 49 + x² + 14xThat 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 sideand not even have to mess with it again.
