Answer:
let ratios be x
2x +3x+4x=180(Sum of triangles)
x=20`
2X=20
x=20×2
X=40
3x=20
X=60
4x=20
x=80
largest angle is 80

Answer:
80°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the parts of the ratio, 2 + 3 + 4 = 9 parts
Divide 180° by 9 to find the value of one part of the ratio
180° ÷ 9 = 20° ← value of 1 part of ratio, then
2 parts = 2 × 20° = 40°
3 parts = 3 × 20° = 60°
4 parts = 4 × 20° = 80°
The measure of the largest angle is 80°
