hope it helps u mark me as brainlist and like my answer pls
Step-by-step explanation:
ratio of 3 angles=2:3:4
let angle 1. be 2x
angle 2 be 3x
angle 3 be 4x
2x+3x+4x=180(sum of angles of triangle is 180 orrr angle sum property)
9x=180
x=180÷9
x=20 degree
angle 1 =2x=2×20=40 degree
angle 2=3x=3×20=60 degree
angle 3=4x=20×4=80 degree
for verification add all angles if sum is 180 answer is correct
verification
40+60+80=180
180=180
so answer is correct
