Question 95850
This type question is frequently on SAT tests.
We have an isoscles right trangle with a hypotenuse of 8.
it is similar to a triangle with sides of 1 and 1 and a hypotenuse of        {{{sqrt(2)}}}
we can solve the problem without using the pythagorean theorum by setting up a ratio. 
{{{x/1=8/sqrt(2)}}}Answer
