Per Pythagoras:
\n" ); document.write( " $\"h=+sqrt%28a%5E2%2Bb%5E2%29\"$ Let's square both sides to get rid of the root:
\n" ); document.write( " $\"h%5E2=+a%5E2%2Bb%5E2\"$ We know one leg, let's say it's a. So:
\n" ); document.write( " $\"h%5E2-a%5E2=b%5E2\"$ Substitute with numbers:
\n" ); document.write( " $\"7.2%5E2-6.4%5E2=+b%5E2\"$
\n" ); document.write( " $\"51.84-40.96=+b%5E2\"$ Subtract on left, they take the square on both sides, and you get:
\n" ); document.write( "b= 3.30
\n" ); document.write( " \n" ); document.write( "
