To find the length of side \( x \) given that one side measures \( 12 \) and the angle \( \theta \) is \( 44^\circ \), we need to know the context in which these measurements are provided.

Assuming you are dealing with a right triangle where:

  • \( 12 \) is the length of the adjacent side to angle \( \theta \), and
  • \( x \) is the opposite side,

You can use the tangent function, which is defined as:

\[ \tan(\theta) = \frac{\text{opposite}}{\text{adjacent}} \]

Thus,

\[ \tan(44^\circ) = \frac{x}{12} \]

To find \( x \), rearrange the equation:

\[ x = 12 \cdot \tan(44^\circ) \]

Now, we can calculate this value. First, find \( \tan(44^\circ) \):

Using a calculator:

\[ \tan(44^\circ) \approx 0.9657 \]

Now plug this value into the equation:

\[ x = 12 \cdot 0.9657 \approx 11.5884 \]

Now round to the nearest hundredth:

\[ x \approx 11.59 \]

Thus, the length of side \( x \) is approximately \( \boxed{11.59} \).
