# How do you do this problem?

Answer: The pythagorean theorem states that a² + b² = c².
We have a = 10 and c = 20.
100 + b² = 400
Subtract 100 from each side.
b² = 300
Get the square root of 300.
It could be expressed as b ≈ 17.321, or could stay in radical form as

Will the opposite of a number always,sometimes,or never be greater than the number itself

OK.  Thanks for clarifying that.

-- If the original number is negative, then its opposite is greater.

-- If the original number is positive, then its opposite is smaller.

-- So the opposite of a number is sometimes greater than the number itself.

it can be greater
example -3 the opposite is 3
it can be smaller
