Answer

40°

Step-by-step explanation:

3 angles of triangle

2x + 4x. + 3x = 180° ( क्युकी त्रिभूज के कोनो की बेरीज 180° होती है )

2x + 4x +3x = 180°

9x = 180 / 9

x = 20

2x = 20×2 ( first angle = 40°)

4x = 20×4. (second angle = 80°)

3x = 20×3 ( third angle = 60° )

therefore the smallest angle will 40°

Answer:

let common ratio be :-x

and we all know that sum of all the angle of a triangle is 180 degree

so 2x+4x+3x =180

9x=180

x=180/9

x=20

so smaleet angel will be 2x=40degree
