    Answer: (3) 45o, 60o, 75o.

    Explanation:-
    The ratio of three angles = 3: 4: 5
    Let the three angles of a triangle are 3X, 4X and 5X

    Then, 3X + 4X + 5X = 180
    12 X = 180
    X = 180/12
    X = 15o

    Then, the angles are 3X = 3 x 15 = 45o, 4 X = 4 x 15 = 60o, 5 x 15 = 75o

    Hence, the answer is (3) 45o, 60o, 75o.
