Question

If angles of a triangle are in the ratio of 2:3:4. Find the value of each angle

Answer 1

Answer:

2x+3x+4x=180(angle sum property of Δ)

9x=180

x=180/9

x=20

so 2x=40

3x=60

4x=80

Answer 2

Answer:

40°,60°,80°

Step-by-step explanation:

Let the ratio be ,2x ,3x and 4x

A/q

2x + 3x + 4x = 180°(Angle sum prop. of ∆)

9x = 180°

x = 20°

<1 = 2x = 40°

<2 = 3x = 60°

<3 = 4x = 80°
