Question

3. The angles of a triangle are in the ratio of 2: 3: 4:. find the angle.​

Answer 1

Answer:

The angles are 40,60,and 80

Step-by-step explanation:

The given ratio is 2:3:4. So we will mark them as 2x, 3x and 4x. As we already know that the total sum of interior angles of a triangle is 180.

So now 2x+3x+4x=180

9x=180

x=20

Therefore the angles are 2x=40 degrees, 3x=60 degrees and 4x=80 degrees.

So i hope that you get it.

Answer 2

Step-by-step explanation:

2:3:4 are the angles of triangle

2x+3x+4x=180.

9x=180.(180 because the total angle of triangle is 180)

x=180/9

x=20,

1 angle:-2*20=40;

2angle:-3*20=60;

3angle:-4*20=80;
