Pythagoras:
\n" ); document.write( "The square of the hypotenuse is equal to the sums of the squares of the sides. And our sides are the same length because it's a square, so we will call our sides \"s\"
\n" ); document.write( " $\"h%5E2=+s%5E2%2Bs%5E2\"$ Add s on right
\n" ); document.write( " $\"h=+2s%5E2\"$ Divide both sides by 2
\n" ); document.write( " $\"h%5E2%2F2=+s%5E2\"$ Now let's plug in our number
\n" ); document.write( " $\"130%5E2%2F2=+s%5E2\"$ Do the math in your calculator and you get:
\n" ); document.write( " $\"16900%2F2=+s%5E2\"$
\n" ); document.write( " $\"8450=+s%5E2\"$ Let's take the square root of both sides to get rid of the exponent:
\n" ); document.write( "91.9= s Each of the sides measures 91.9
\n" ); document.write( " \n" ); document.write( "
