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
