Answer:

            A + B = 2κπ -  C    , κ∈Z  or  A + B = 2κπ + π  + C , κ∈Z

Step-by-step explanation:

   sin(A + B) = -sin C

   sin(A + B) = sin( - C)

   A + B = 2κπ + (-C) , κ∈Z  or  A + B = 2κπ + π - (-C) , κ∈Z

   A + B = 2κπ -  C    , κ∈Z  or  A + B = 2κπ + π  + C , κ∈Z

where:

  • κ is an integer
  • π is pi, the well known 3,14....
