That's... Pythagoras not Einstein, and if that's the joke good on you I guess.

a^2+b^2=c^2

c^2 is the Hypotenuse (Angled one), which means we'll make the 4 a^2, and now we're solving for b^2 (the unknown)

If a^2+b^2=c^2, then that means that c^2-a^2 would equal b^2

SO, put numbers in, and that means:

5^2 - 4^2 = x^2
(5x5) - (4x4) = x^2
25 -16 = x^2
9=x^2
Since we still have the x as an exponent of two, we square root each side to cancel it out (Opposite functions cancel out, and what you do to one side must be done to the other)

SO, finally, we take the square root of 9, which is 3, and there's you're answer!

X=3

Sure bro... In a triangle where you have one 90° angle the following relation holds true: The square of the side that is opposite to the 90° angle is equal to the squares of the other two sides combined. In this case the side opposite to the 90° angle is 5, the other two sides are 4 and x. So:


5^2 = 4^2 + x^2
25 = 16 + x^2
x^2 = 25-16 = 9

-> x = 3 or x = -3, but negative lengths don't make sense here, so x = 3.
