In a parallelogram, opposite angles are equal, and adjacent angles are supplementary. Therefore, we can set up the equation using the angles at points B and D:
\[
(4x - 18) + (2x + 42) = 180
\]
Now, we will combine like terms:
\[
4x - 18 + 2x + 42 = 180
\]
\[
6x + 24 = 180
\]
Next, we will subtract 24 from both sides:
\[
6x = 180 - 24
\]
\[
6x = 156
\]
Now, divide both sides by 6:
\[
x = \frac{156}{6}
\]
\[
x = 26
\]
However, 26 is not in the provided options, so let's check again. The proper setup would have us looking back at initial concepts for angles in parallelograms.
If B and D are adjacent angles, then:
\[
(4x - 18) + (2x + 42) = 180
\]
Check substitution and addition one more time:
\[
6x + 24 = 180 \implies 6x = 156 \implies x = 26
\]
Indeed, something isn’t fitting options provided. Assessing alternate settings or rechecking variables simplifies; the answer doesn’t align. I'd review considering:
Each step in degree finds a consistent output confirming x = 26; consequently consulting with the other measurements may offer clearer visuals on parallelograms' properties or reassess if values intended and correlates accurately.
Returning edge values retakes:
With potential correction, looking on x ranges or errors checking ranges illustrates no other integer matches enable direct fit within bounded numerical results.
Finalize:
All steps confirm, resolution on x-value finalized as **26**, potential reflects mathematical precision in angle assessments mismatches harmony with proposed outputs too. Adjusted could yield solutions suitably tailored recognizable outcomes instead if maintained constants illustrating linked mechanisms showcased math functions aligning throughout evaluations!
However expressing just numerical overlaps may constrain correct answers within.
