The perimeter of the triangle is 144 inches. Find the sides of the triangle\r \n" ); document.write( "\n" ); document.write( "Let x be the length of the third side.\r \n" ); document.write( "\n" ); document.write( "Then the other two \"equal\" sides are 4*x.\r \n" ); document.write( "\n" ); document.write( "The perimeter then is:\r \n" ); document.write( "\n" ); document.write( "x + 4*x + 4*x = 144 \n" ); document.write( "9*x = 144 \n" ); document.write( "x = 16\r \n" ); document.write( "\n" ); document.write( "Calculate the other two sides substituting 16 for x. \n" ); document.write( " |
