Question 293932
THe lengths of the 3 sides are:
x, 16+x & 2+x
x^2+(2+x)^2=(16+x)^2
x^2+4+4x+x^2=256+32x+x^2
2x^2-x^2+4x-32x+4-256=0
x^2-28x-252=0
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} 
x=(28+-sqrt[-28^2-4*1*-252])/2*1
x=(28+-sqrt[784+1,008])/2
x=(28+-sqrt1,792)/2
x=(28+-42.332)/2
x=(28+42.332)/2
x=70.332/2
x=35.166 ans.
x=(28-42.332)/2
x=-14.332/2
x=-7.166 ans.
