mark me as the brainliest

Answer 2

Answer:

Answer is angle 4

Step-by-step explanation:

the interiar angle of the triangle are 2:3:4

let the interior angle of the triangle be X

so,

2x:3x:4x

we will put angle property of triangle

sum of all side

a°+b°+c°=180°

2x° + 3x° + 4x° = 180°

9x° = 180°

X° = 180/9

X°=20

so,

2*20=40

3*20=60

4*20=80

angle 4 is the greatest side of the triangle
