Square Barn
Okay. Here's the full explanation. I'll work out the numbers
on the next page,
3/4 of a 50 foot radius circle + 2 wedges of a 40 foot circle + 1 triangle  1/2 the barn.
we know all three sides of the triangle. I hope you know at least
beginning trigonometry. Knowing the three sides of the triangle, we can find all the
angles and the area. You need to find the lower angle of the triangle and
subtract from 135. That will be the angle of the wedges.
