a = √25 = 5

b = √32 = 5.656854249

c = AB = ?

∠C = 81.86989765º

The law of cosines:          c² = a² + b² - 2ab * cos(C)

                                         c² = 25 + 32 - 56.56854249 * 0.141421356

                                         c² = 57 - 8

                                         c = 7  indecision
