    Step-by-step explanation:

    The exterior angle measure the same as the 2 angles more far away from the exterior

    So 2 angles measure together 150 and the other angle 30

    It could be

    75+75+30

    85+65+30

    70+80+30

    Be careful that some combinations resulting in 150 cannot form a triangle

    For instance

    100+50+30

    Because the sum of 30+50 IS NOT bigger than 100

    Condition for a triangle is that the sum of 2 sides is bigger than the 3rd sides. And it should be for all sides

    Ex: 100+30 is bigger than 50

    BUT

    50 + 30 is not bigger than 100

    So this combination is not possible
