Algebra.Com's Answer #834956 by Theo(13342)![]() ![]() You can put this solution on YOUR website! the isosceles rriangle short side is half the length of one of the long sides. \n" ); document.write( "the let x = the length of the short side. \n" ); document.write( "2x = the length of one of the long sides. \n" ); document.write( "2x = the length of the other long side, since this is an isosceles triangle which means that 2 sides are of equal length. \n" ); document.write( "the perimeter of the triangle is therefore x + 2x + 2x = 5x. \n" ); document.write( "since the perimeter is 15, then 5x = 15 which makes x = 3. \n" ); document.write( "the length of the short side is 3. \n" ); document.write( "the length of the long sides is 6 each.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
