x=
​

Answer 1

x=12°

Explanation:

When you add the following angles, you get 180 degrees.

Because of this, we can set up and equation.

`10x-20+6x+8=180`

Combine like terms

`16x-12=180`

Then add 12 to both sides

`16x=192`

Divide

`x=12`

Add label

x=12°

Answer 2

12

Explanation:

since these angles are supplementary, they equal 180. So set 10x-20+6x+8=0 and solve. add 12, divide by 16.
