    (sin119) / 128=sinB/106

    sinB=106 (sin119) / 128

    B=arcsin (106 (sin119) / 128)

    B≈46.41°

    C≈ (180-119-46.41) = 14.59°

    (sin119) / 128 = (sin14.59) / c

    c=128 (sin14.59) / sin119

    c≈36.87

    So the sides a, b, c are 128, 106, 36.87 respectively and

    angles a, b, c are 119°, 46.41°, 14.69° respectively.
