The angle you want - call it <em>θ</em> - is such that

tan(<em>θ</em>) = FC / AC

Find the length of the diagonal AC, i.e. a diagonal of the rectangle ABCD. ABC forms a right triangle with legs AB = 70 and BC = 50, so

AC² = AB² + BC²

→   AC = √(70² + 50²) = 10 √74

Find FC using the given angle of the sloping face:

tan(30º) = FC / BC

→   1/√3 = FC / 50

→   FC = 50/√3

Now solve for <em>θ</em> :

tan(<em>θ</em>) = (50/√3) / (10 √74)

→   tan(<em>θ</em>) = 5/√222

→   <em>θ</em> ≈ 18.6º
