Question

Interior angles of a triangle are in the ratio 2 : 3 : 4. Find the angles of the triangle.

Answer 1

Answer:

Let the angles be 2x, 3x, 4x

B.T.Q,

2x + 3x + 4x = 180

9x = 180

x = 180/9

  = 20

2x = 20 * 2

    = 40

3x = 20 * 3

    = 60

4x = 20 * 4

     = 80

Ans- 40, 60, 80

Step-by-step explanation:

Answer 2

Answer:

let the unit be X

therefore, 2x, 3x and 4x

the sum of all angles in triangle is 180°

=> 2x +3x +4x = 180°

9x = 180°

X= 180°/9

X= 20

therefore the angles are as follows

2×20= 40

3×20=60

4×20=80
