c. 40degree
plz answer this if you answer correct I will make brainlest ​

Answer 1

2x + 3x + 4x + 9x =360

18x = 360

x = 360 ÷ 18

x = 20

so smallest angle is

2× 20 = 40

Answer 2

Answer:

40°

Step-by-step explanation:

let the angles are

2x:3x:4x:9x

sum=2x+3x+4x+9x=360

18x=360

x=360/18=20

smallest angle=2x=2*20=40°
