The image shows a diagram with two intersecting lines forming an exterior angle of \(133^\circ\) and another expression given as \(x + 138^\circ\). The problem asks to solve for \(x\).

We are dealing with a pair of supplementary angles here, as they lie on a straight line and sum to \(180^\circ\).

Let's set up the equation:
\[
x + 138^\circ + 133^\circ = 180^\circ
\]

Now solve for \(x\):
\[
x + 271^\circ = 180^\circ
\]
\[
x = 180^\circ - 271^\circ
\]
\[
x = -91^\circ
\]

It seems there may have been a mistake in setup, as the answers provided are positive or much smaller in magnitude. On closer inspection, let's consider an alternative setup that treats the \(x + 138^\circ\) as the vertical angle to \(133^\circ\), making them equal:
\[
x + 138^\circ = 133^\circ
\]

Solving this:
\[
x = 133^\circ - 138^\circ
\]
\[
x = -5
\]

Thus, the correct value of \(x\) is \(-5\), corresponding to option **D**.

Would you like further details or have any questions? Here are 5 related questions to expand on this:

1. What are supplementary angles and how do they relate to straight lines?
2. Can you explain the concept of vertical angles in more detail?
3. How do we distinguish between different angle relationships in intersecting lines?
4. What other types of angles could be formed by intersecting lines and parallel lines?
5. How would the equation change if the angles were complementary instead of supplementary?

**Tip**: Always check for vertical angles and parallel lines when dealing with angle problems, as they often simplify the solution process!

Solve for x given the angle relationship in the diagram, where the angles are labeled as (x + 138)° and 133°.
