    Answer:

    45  60  75

    Step-by-step explanation:

    Let’s call the angles 3 x , 4 x and 5 x

    They must add up to 180 o in a triangle, so:

    3 x + 4 x + 5 x = 12 x = 180 → x = 180 / 12 = 15 So the angles are:

    3 ⋅ 15 = 45 o 4 ⋅ 15 = 60 o 5 ⋅ 15 = 75 o Check answer:

    45 + 60 + 75 = 180
