Question

the angle of a triangle are in the ratio 2:4:3 which value of the smallest angle​

Answer 1

Answer

40

Step-by-step explanation:

Let x = 2x, 4x, 3x,

by triangle sum property

2x+3x+4x = 180

9x =180

x = 180/9

x = 20

x = 2*20

= 40

x = 4*20

= 80

x =3*20

= 60

40,80,60

so smallest angle are 40

Answer 2

2x= 2*20°=40°

Step-by-step explanation:

let ratio of three angle of triangle be 2x,3x,4x

sum of angle of triangle is180 degree

according to question

2x+3x+4x=180°

9x=180°

x=180°/9

x=20°

smallest angle=2x=2*20°=40°
