Let x = common angle,,,,,smaller angle = x/4 \n" ); document.write( ". \n" ); document.write( "Remember that the sum of the interior angles of a triangle = 180 \n" ); document.write( ". \n" ); document.write( "x+x+x/4 =180 \n" ); document.write( ". \n" ); document.write( "2.25x = 180 \n" ); document.write( ", \n" ); document.write( "x=80 \n" ); document.write( ". \n" ); document.write( "angles of triangle are,,,,,80,,,80,,,20 \n" ); document.write( ". \n" ); document.write( "check,,, sum to 180,,,,ok \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( " |
