When SSA data gives two triangles, the two angles at B (call them B1 and B2) are:

  1. equal
  2. complementary
  3. supplementary (B1 + B2 = 180^circ)
  4. both right angles
Answer

C) supplementary (B1 + B2 = 180^circ)

The two positions of B form an isosceles triangle with C, so the angles add to 180^circ. SLO M-09-B-30 · Knowledge
