Solve for X: Finding Angles 3X+80 and X+85 in Intersecting Lines

To solve this problem, we need to establish the relationship between the given angles, $3X + 80$ and $X + 85$. In a typical parallel line scenario, these might be corresponding angles, alternate interior angles, or supplementary angles under various configurations.

However, the problem does not supply enough information about the geometric or angular relationships between these given angles. Without knowing the specific arrangement of lines or angles (e.g., which line is a transversal, or whether these angles form certain kinds of angle pairs), we cannot definitively say how the angles are related.

In standard parallel line setups, angles such as corresponding or alternate interior angles must be equal, but the problem does not confirm these angles belong to such categories. Thus, without additional context or diagrams clarifying how these angles align with properties of parallel lines, we cannot validly calculate $X$ simply based on the given expressions.

Therefore, based on the typical angles-in-parallel-lines context and the information given, we conclude it is not possible to calculate $X$ or determine the value of the marked angles.

The correct choice that reflects this understanding is: It is not possible to calculate.
