A)The angles are neither complementary nor supplementary.
Complementary- Two angles whose sum add up to 90° ( a right angle)
Supplementary-Two angels whose sum when added together is 180°
It seems to be a obtuse angle - more than 90° but less than 180°
Let the measures of three angles be 2x, 9x, 4x
Sum of the angles of a triangle = 180
2x+9x+4x = 180
15x = 180
x = 180/15 = 12
First angle = 2x = 2*12 = 24°
Second angle = 9x = 9*12 = 108°
Third angle = 4x = 4*12 = 48°
