If the perimeter of the diamond is 8cm and the height is 1cm, then the degree ratio of the two adjacent angles of the diamond is?

If the perimeter of the diamond is 8cm and the height is 1cm, then the degree ratio of the two adjacent angles of the diamond is?

Perimeter 8, side length is 2
If the height is 1 and the side length is 2, the acute angle of the diamond is 30 degrees, then the other angle is 150 degrees
The ratio of adjacent angles is 1:5
