\"a%5E2%2Bb%5E2=c%5E2\"
\n" ); document.write( "c = 22.8
\n" ); document.write( "Let a be the longer leg
\n" ); document.write( "a = 2b
\n" ); document.write( "substituting we have
\n" ); document.write( "\"%282b%29%5E2%2Bb%5E2=22.8%5E2\"
\n" ); document.write( "\"4b%5E2%2Bb%5E2=22.8%5E2\"
\n" ); document.write( "\"5b%5E2=22.8%5E2\"
\n" ); document.write( "divide each side by 5
\n" ); document.write( "\"b%5E2=22.8%5E2%2F5\"
\n" ); document.write( "take the square root of each side
\n" ); document.write( "\"b=sqrt%2822.8%5E2%2F5%29\"
\n" ); document.write( "b = 10.196
\n" ); document.write( "a = 2b = 2*10.196 = 20.392
\n" ); document.write( "
