    Answer:

    45, 60,75

    Step-by-step explanation:

    Let angles be:3x,4x,5x,

    Sum of all angle of triangle=180

    3x+4x+5x=180

    12x=180

    x=180/12

    x=15

    So angle are 45,60 and 75.

    Step-by-step explanation:

    Let their sides are 3x , 4x, 5x

    A/Q,

    perimeter of triangle = 3x + 4x + 5x = 48

    => 12x = 48

    => x = 4

    Then sides are 12cm , 16cm , 20 cm
