    2:4:9

    so 2 + 4 + 9 = 15

    180/15 = 12

    12*2 = 24

    12*4 = 48

    12*9 = 108

    measures of the angles 2:4:9 = 24:48:108

    Sum of all angles in a triangle is 180 degrees. If we mark angles as a, b and c, from given ratio we would have: a + b + c = 180 a = 2x b = 4x c = 9x 2x + 4x + 9x = 180 15x = 180 x = 12 a = 2x = 24 b = 4x = 48 c = 9x = 118
