Question

9. If angles of a triangle are in the ratio 2 : 3: 4, the angles are

2 points

50,60,70

65,105,10

40,60,80

80,30,70

​

Answer 1

Answer:

The angles are 40,60,80

Step-by-step explanation:

Let the common angle be x

2x+3x+4x=180

9x=180

x=20

Answer 2

Solution....

Let the angles of triangles be 2x, 3x and 4x.

The sum of angles of an triangle is 180.

Now,

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

=> 9x = 180...

=>x = 180/90

So, x = 20...

Now put the x =20 in given angles...

Therefore, 2x= 2*20 = 40

3x = 3*20=60

4x=4*20=80
