1. tanB = b/a = 250 / a,
a = 250 / tanB = 250 / tan51.52 = 198.7
A = 90  51.52 = 38.5 deg.
c = b / cosA = 250 / cos38.5 = 319.4.
2. B = 90  A = 90  27.83 = 62.17 deg.
tanA = a / b = 530 / b,
b = 530 / tanA = 530 / tan27.83 = 1004.
c = a / sinA = 530 / sin27.83 = 1135.3.
3. sinB = b/c,
b = csinB.
4. tanA = a/b,
b = a/tanA.
