~~~~~~~~~~~~~~~~~~~~~~~

(1) x = 180 - 80 - 88 degrees.

(2) the last line in the "condition" is irrelevant to the problem.

==================================

The answer x = 22 in the post by @josgarithmetic is an ERROR.

The value of angle $x$ is **12 degrees**.
## 📐 Calculation
The sum of the interior angles in any triangle is always **$180^\circ$**.
You are given the three angles of the triangle as $x$, $80^\circ$, and $88^\circ$.
$$x + 80^\circ + 88^\circ = 180^\circ$$
1. **Sum the known angles:**
$$80^\circ + 88^\circ = 168^\circ$$
2. **Solve for $x$:**
$$x + 168^\circ = 180^\circ$$
$$x = 180^\circ - 168^\circ$$
$$x = 12^\circ$$
Therefore, angle $x$ is **$12$ degrees**.
