Answer:

18, 54, 108

Step-by-step explanation:

Let the first angle is ‘x’

Second angle =3x

Third angle=2(3x)=6x

Sum of the three angles of a triangle =180 degrees

x+3x+6x=180

x=18

The first angle is 18,second angle is (3*18)=54.third angle is (6*18)=108

The angles are 18,54 and 108 degrees

Here you have x + 3x + 72 = 180. By isolating the variable by dividing on both sides, the answer is x = 27
