$\"a%5E2\"$ + $\"b%5E2\"$ = $\"c%5E2\"$
\n" ); document.write( "c, the hypotenuse, is given as 20m
\n" ); document.write( "One side is given as 15.4m
\n" ); document.write( "Plug in the numbers
\n" ); document.write( " $\"15.4%5E2\"$ + $\"b%5E2\"$ = $\"20%5E2\"$
\n" ); document.write( "237.16 + $\"b%5E2\"$ = 400
\n" ); document.write( "Subtract 237.16 from each side
\n" ); document.write( " $\"b%5E2\"$ = 162.84
\n" ); document.write( "Take the square root of each side
\n" ); document.write( "b = 12.76 (rounded) \n" ); document.write( "

\n" );
