The hypotenuse is the longer side of a right triangle.
\n" ); document.write( "The other two sides of a right triangle are called legs.
\n" ); document.write( "\"x\"= length of one of the legs, in mm.
\n" ); document.write( "\"y\"= length of the other leg, in mm.
\n" ); document.write( "
\n" ); document.write( "The perimeter is 90mm gives us the equation
\n" ); document.write( "\"x%2By%2B41=90\"<--->\"x%2By=90-41\"<--->\"x%2By=49\"<--->\"y=49-x\"
\n" ); document.write( "
\n" ); document.write( "The Pythagorean theorem, applied to this particular triangle, tells us that
\n" ); document.write( "\"x%5E2%2By%5E2=41%5E2\"<--->\"x%5E2%2By%5E2=1681\"
\n" ); document.write( "
\n" ); document.write( "\"system%28y=49-x%2Cx%5E2%2By%5E2=1681%29\"--->\"system%28y=49-x%2Cx%5E2%2B%2849-x%29%5E2=1681%29\"--->\"system%28y=49-x%2Cx%5E2%2B2401-98x%2Bx%5E2=1681%29\"--->\"system%28y=49-x%2C2x%5E2-98x%2B720=0%29\"--->\"system%28y=49-x%2Cx%5E2-49x%2B360=0%29\"
\n" ); document.write( "\"x%5E2-49x%2B360=0\"--->\"%28x-40%29%28x-9%29=0\"--->\"system%28x=40%2C%22or%22%2Cx=9%29\"
\n" ); document.write( "and those are the lengths (in mm) of the legs of the right triangle, because
\n" ); document.write( "\"system%28y=49-x%2Cx=40%29\"--->\"system%28y=9%2Cx=40%29\" and \"system%28y=49-x%2Cx=9%29\"--->\"system%28y=40%2Cx=9%29\" .
\n" ); document.write( "Either way, lengths of the other two sides of the right triangle are
\n" ); document.write( "\"highlight%2840mm%29\" and \"highlight%289mm%29\" .
\n" ); document.write( "
\n" );
