Angle A + Angle B + Angle C = 180 degrees. If one angle equals 90 degrees then it is a right triangle and the lengths of the sides are in a ratio such that A squared plus B squared equals C squared (Pythagorean Theorem)

X = √63
b = 14324.80366
2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.
