The problem presents a triangle with two labeled angles and sides. To determine the value of \( x \), let's break it down:

### Given:
- One angle is \( 110^\circ \).
- The other two angles are not given directly but the sum of all angles in a triangle must be \( 180^\circ \).
- The two other angles are labeled as:
  - \( x + 10^\circ \) (one unknown angle)
  - \( 2x^\circ \) (another unknown angle)

### Steps:
1. The sum of the interior angles in any triangle is always \( 180^\circ \). Therefore, we can write the equation for the angles:
   \[
   110^\circ + (x + 10^\circ) + 2x = 180^\circ
   \]
2. Simplifying this equation:
   \[
   110 + x + 10 + 2x = 180
   \]
   \[
   3x + 120 = 180
   \]
3. Subtract \( 120 \) from both sides:
   \[
   3x = 60
   \]
4. Solve for \( x \):
   \[
   x = \frac{60}{3} = 20
   \]

Now that \( x = 20^\circ \), we can substitute it back into the expressions for the angles:
- \( x + 10 = 30^\circ \)
- \( 2x = 40^\circ \)

The three angles are:
- \( 110^\circ \)
- \( 30^\circ \)
- \( 40^\circ \)

Clearly, these do not sum up to \( 180^\circ \), which means there was an error in the labeling or interpretation.

Based on the options provided, let's test \( x = 33.33^\circ \) (D) which might fit the triangle constraints better.

Would you like me to clarify this further? Let me know if you need any details.

Here are five related questions:
1. How do the sum of angles in any polygon differ from that in a triangle?
2. What is the property of exterior angles in a triangle?
3. How can you verify the properties of an isosceles triangle?
4. What is the difference between acute, obtuse, and right angles in geometry?
5. Can you explain why triangles have the same angle sum regardless of size?

**Tip:** Always double-check whether the triangle provided could have rounding or missing information if the angle sums seem incorrect.
