Answer:
X=20
Explanation:
As you should know to solve this a line equal 180 degrees. And because they are both on the opposite side of each other than you need to make an equation. That equation would be 6x-4+3x+4=180.
6x-4+3x+4=180
combine all the like terms
9x+0=180
divide the 9 on both sides
20= x
In this case I believe you would be finding X but if I am wrong and you are not finding X then switch the X in the equations to 20 and you will have your answer for both sides. HOPE THIS HELP!
