If the perimeter of the diamond is 40cm and the ratio of the two adjacent angles is 1:2, the length of the shorter diagonal depends on the process

The sum of two adjacent angles is 180 degrees, 1:2 can get one is 60 degrees, one is 120 degrees, the perimeter is 40cm, the side length is 10cm, the shorter diagonal and both sides form an equilateral triangle, so the shorter diagonal is equal to the side length is equal to 10cm
