Answer 1

Step-by-step explanation:

let the Angles be 2x,3x and 4x

so,

2x+3x+4x=180

9x=180

x=20

so,

2x=2×20

=40

3x=3×20

=60

4x=4×20

=80

Answer 2

Answer:

let common ratio is equals to X

so 2x,3x,4x

sum of angles of triangle is equals to 180 degree

2x+3x+4x=180degree

9x=180

x=180/9

x=20

2x equals to 2×20=40°

3x equals to3×20=60°

4x equals to4×20=80°

now you can add 40 degree + 60 degree + 80 degree it is 180 degree

so answer is correct
