Perhaps it would be better if you provide us with the specific problem you're looking at. This way, it'll be a little easier to explain.\r
\n" ); document.write( "\n" ); document.write( "Basically, if you have a \"right-triangle\" (one of the three interior angles measures 90 degrees), then you can apply the formula:
\n" ); document.write( "a^2 + b^2 = c^2
\n" ); document.write( "where
\n" ); document.write( "c is the hypotenuse (longest side)
\n" ); document.write( "a and b are the other two sides
\n" ); document.write( ".
\n" ); document.write( "for example, say you have a=3 and b=5 and you're looking for the hypotenuse then
\n" ); document.write( "3^2 + 4^2 = c^2
\n" ); document.write( "9 + 16 = c^2
\n" ); document.write( "25 = c^2
\n" ); document.write( "now, you would take the square root of both sides:
\n" ); document.write( "5 = c
\n" ); document.write( "
\n" ); document.write( "
\n" );
