Triangle angles always add up to 180 degrees.
So what you’ll need to do is add up all the angles and set them equal to 180. And then solve for x

4x+3x+2x=180 | Add up all values
9x=180 | Divide 180 by 9
x=20 | There’s your answer

Answer:

X=20

Step-by-step explanation:

To solve this problem, first you have to find the value of x. Remember to solve this problem, isolate x on one side of the equation.

4x+3x+2x=180

4x+3x+2x (First, combine like terms, group like terms.)

4x+3x+2x (Solve & add.)

4x+3x+2x=9x

9x=180

9x/9=180/9 (Then, divide by 9 from both sides.)

180/9 (Solve.)

180/9=20

x=20

So, the correct answer is x=20.
