Question

The angles are in the ratio 2:3:4.​

Answer 1

Answer:

2x+3x+4x=180

9x=180

x=20

So, 2x=2×20=40

So,3x=3×20=60

So,4x=4×20=80

Answer 2

Answer:

Ratio = 2:3:4

Let the three angles of the triangle be

2x + 3x + 4x

So, 2x + 3x + 4x = 180° (Angle sum property)

9x = 180°

x = 180/9

x = 20°

2x = 2 × 20 = 40

3x = 3 × 20 = 60

4x = 4 × 20 = 80
