a = 4.5
\n" ); document.write( "c = 10
\n" ); document.write( "Plug these in
\n" ); document.write( " $\"+a%5E2+%2B+b%5E2+=+c%5E2+\"$
\n" ); document.write( " $\"+4.5%5E2+%2B+b%5E2+=+10%5E2+\"$
\n" ); document.write( " $\"+20.25+%2B+b%5E2+=+100+\"$
\n" ); document.write( "subtract 20.25 from both sides
\n" ); document.write( " $\"+b%5E2+=+79.75+\"$
\n" ); document.write( "Square root both sides
\n" ); document.write( " $\"+b+=+sqrt%2879.75%29+\"$
\n" ); document.write( "b is approx 8.9 inches \n" ); document.write( "
