Question 810260
Assuming this is a right triangle.
base=x
height=x+2
hypotenuse=10
use the pythagorean theorem.
{{{a^2+b^2=c^2}}}
{{{x^2+(2+x)^2=10^2}}}
{{{x^2+4+x^2=100}}}
{{{2x^2=96}}}
{{{x^2=48}}}
{{{x=sqrt(48)}}}
simplify
{{{x=4sqrt(3)}}}
so the base is {{{4sqrt(3)}}}
and the height is {{{2+4sqrt(3)}}}
