Answer:

  0.5 cm

Step-by-step explanation:

I prefer to write the proportion so the unknown value is in the numerator.

  c/sin(C) = b/sin(B)

  c = b×sin(C)/sin(B) = (2 cm)×sin(15°)/sin(105°) ≈ 0.535898 cm

  c ≈ 0.5 cm

_____

For those of you looking for 'a', that value is shown in the attachment.
