To find the angle \( Z \) given \( \cos Z = 0.4384 \), we can use the inverse cosine function (arccos).

Using a calculator, we can find:

\[ Z = \cos^{-1}(0.4384) \]

Calculating this gives:

\[ Z \approx 64.5° \]

Rounding to the nearest degree results in:

\[ Z \approx 65° \]

Since this exact answer is not listed in the options, let's check which of the provided options is closest. The given options are:

1. 64°
2. 39°
3. 1°
4. 30°

The closest answer to 65° is **64°**.

Therefore, the correct answer is **64°**.
