\n" );
document.write( "so c = 90, and a = 45 I am solving for b.
\n" );
document.write( "this is what I did but I don't think it is correct because the final answer is not an even square.
\n" );
document.write( "45^2 + b^2 = 90^2
\n" );
document.write( "2025 + b^2 = 8100
\n" );

document.write( "b^2 = 6075
