The angles of a triangle are 2x, 3x, and 4x degrees. Find the value of x.

Solution:

Given, the angles of a triangle are 2x, 3x and 4x degrees.

We have to find the value of x.

We know, the sum of interior angles of a triangle is always equal to 180 degrees.

Now, 2x + 3x + 4x = 180°

5x + 4x = 180°

9x = 180°

x = 180°/9

x = 20°

Therefore, the value of x is 20°.

The angles of a triangle are 2x, 3x, and 4x degrees. Find the value of x.

Summary:

The angles of a triangle are 2x, 3x, and 4x degrees. The value of x is 20°.
