WebLet's suppose that you know a triangle has angles 90 and 50 and you want to know the third angle. Let's call the unknown angle x. x + 90 + 50 = 180 x + 140 = 180 x = 180 - 140 x = 40 As for the side lengths of the triangle, you need more information to figure those out. http://www.wallace.ccfaculty.org/book/10.8%20Inverse%20Trig.pdf
