Question

What is the value of X?

Answer 1

x = 21

Explanation:

The two angles are supplementary angles, meaning that the sum of both angles equals 180°.

With this information, we can create an equation that we can use to solve for
`x`.

`6x+2x+12=180`

1. Combine like terms

`8x+12=180`

2. Subtract 12 from both sides.

`8x=168`

3. Divide eight from both sides

`(8x)/(8) =(168)/(8)`

`x=21`
