4x° + 3° + 2x° + 9° = 180°

(4x + 2x)° + (3 + 9)° = 180°

6x° + 12° = 180°

6x° = 180° - 12°

6x° = 168°

x° = 168/6

x° = 28°

So, the value of x is 28°

Hope it helpful and useful :)

Answer:

x=28

Step-by-step explanation:

1. 4x+3+2x+9=180, Imagine a half circle which is 180 degrees where the image is! if you add the 2 equations, you would get 180

2. Add like terms, 6x+12=180

3. 6x=168, then divide 168 by 6

4. x=28

sorry if this is a bad explanation!
