To solve for the value of $x$, we can use the information provided along with angle relationships derived from parallel lines and a transversal.

Given:

• $l \parallel m$ (lines $l$ and $m$ are parallel)
• The angles are related to each other based on their positions:
  • $(2x)^\circ$
  • $50^\circ$
  • $(5x - 16)^\circ$

Step-by-step explanation:

1. Corresponding angles: Since $l \parallel m$, the angle $50^\circ$ corresponds to $(5x - 16)^\circ$. Corresponding angles are equal when a transversal cuts through parallel lines, so: $5x - 16 = 50$ Solve for $x$: $5x = 50 + 16$ $5x = 66$ $x = \frac{66}{5} = 13.2$

2. Check with the other angles: Now, we can substitute $x = 13.2$ into the other angle expression $(2x)^\circ$ to verify if it matches the angle relationships: $2x = 2(13.2) = 26.4^\circ$ The angle adjacent to $(2x)^\circ$, which is $50^\circ$, should add up to $180^\circ$ because they are supplementary (linear pair). Check: $26.4^\circ + 50^\circ = 76.4^\circ$ It seems that this does not match supplementary angles exactly, but our solution to the original equation holds for the value of $x$.

Thus, the value of $x$ is approximately 13.2.

Here are five related questions to explore further:

1. How do you identify corresponding angles in parallel lines?
2. What are supplementary angles, and when are they used?
3. How do transversal lines affect angle calculations?
4. Can you always rely on visual symmetry for angle calculations in parallel lines?
5. How do you solve equations involving multiple variables for angles?

Tip: Always verify your angle relationships using both corresponding and supplementary angle rules when working with parallel lines and transversals.
