Needless to say I am awful at math.
I am trying to figure what the degree of angle is for one of the brooder doors i have to build.

left side: 28 3/8"
right side: 20.5"
base: 46 1/8"
top(angled part): 46.75"

I am hoping someone can tell me how to go about finding the angle. searched all over about right trapezoids/trapeziums, etc. would Really appreciate any help.

Assuming you have square corners, you have a right triangle at the top of 7.825 (28.375 - 20.5) x 46.125 creating an angle of 9.63

I used this triangle calculator.

Hope this helps,

Absent anything else, you could draw it on some cardboard, fiddle with it until the cardboard fits, then make the keeper.
