    Let the second angle be x.

    Second angle = x

    First angle = 3x - 6

    The sum of the two angles is 180°

    x + 3x - 6 = 180

    4x - 6 = 180

    4x = 186

    x = 186 : 4 = 46.5°

    Second angle = 46.5°

    First angle = 3 (46.5) - 6 = 133.5°

    Answer: The angles are 46.5° and 133.5°
