So firstly, thanks to linear pair theorem, we can solve for angle BAC as such:

For that, all you need to do is subtract 122 on each side, and your answer will be 58 = BAC.
Now that we got the two interior angles for triangle BAC, we can use the triangle angle sum theorem to solve for the third angle.

Firstly, combine like terms:

Next, subtract 82 on both sides, and your answer will be x = 98, or D.
