Answer 1

Answer:

The angles are 40°, 60° and 80°

Step-by-step explanation:

Let the common angle be x

And the total of all the angles of a triangle add up to 180°

Threfore,

2x + 3x + 4x = 180°

9x = 180°

x = 180/9

x = 20°

Therefore, the common angle is 20°

The angles are,

2*20= 40°

3*20 = 60°

4*20 = 80°

Answer 2

Step-by-step explanation:

To answer this question, the fact that any triangle's angles sum up to be 180 degrees, will help us a lot.

Since the three angels sum up to be 180 degrees, we could set up an equation to solve it.

Say we set up x for 1 in the 2:3:4 . Now, we add them up.

2x+3x+4x=180

9x=180

x=20

Now that we know what x is, plug them in:

2x=40,3x=60,4x=80.40:60:80

The angles are 40, 60 and 80.
