Answer:

x = 36

Explanation:

1. It's important to know that the sum (in degrees) of all angles in a triangle is 180°.

  • This means that 2x + 2x + x = 180.

2. (Solving)

Step 1: Simplify both sides of the equation.


  • (2x+2x+x)=180

  • 5x = 180

Step 2: Divide both sides by 5.


  • (5x)/(5)=(180)/(5)

  • x = 36

Step 3: Check if solution is correct.


  • 2(36)+2(36)+36=180

  • 72+72+36=180

  • 180=180

Therefore, the answer is 36.
