Question

if the angle of a triangle are in the ratio 2 :3: 4 determine the three angle​

Answer 1

Step-by-step explanation:

let angles be 2x,3x,4x

then,

2x+3x+4x=180

9x=180

x=20

2x=2×20=40

3x=3×20=60

4x=4×20=80

Answer 2

Answer:40,60 and 80

Step-by-step explanation:

lets assume the angles to be 2x,3x and 4x.

We know the angle sum property of triangle is 180.

=> 2x +3x +4x = 180

=> 9x =180

=> x=180/9=20.

Hence the angles are

2x=2*20=40

3x=3*20=60

4x=4*20=80
