right triangle with a hypotenuse of 650 feet, and one side being 600 feet. If so, use the Pythagorean Theorem, with x being the missing side.
X^2 + 600^2 = 650^2
Solve for x

qushak: Are you having trouble solving for x? Steps are: (1) subtract 600^2 from both sides, then (2) take the square root of the result.

SO WOULD IT BE 600^2=360000 AND 650^2=422500
360000-422500=62 500
X=62500

Not quite - you forgot to take the square root as the last step:
x^2 + 600^2 = 650^2\\
x^2 = 650^2 - 600^2 = 422500-360000 = 62500\\
x = \sqrt{62500} = 250
