Question

if the angles are in ratio 2:3:4 find the angles​

Answer 1

Answer:

let the angles be 2x, 3x and 4x

then, 2x+3x+4x = 180°

→ 9x = 180°

→ x. = 180/9

→ x = 20°

therefore, 2x = 2×20° = 40°

3x = 3×20° = 60°

4x = 4×20° = 80°

Answer 2

Step-by-step explanation:

if the angles are in the ratio 2:3:4

so 2:3:4=2x+3x+4x

sum of all sides is 180°

2x+3x+4x=180°

9x=180°

x=180°/9=20°

x=20°
