The image shows a trigonometric problem where the task is to evaluate trigonometric ratios. Specifically, the problem asks to compute:

- a) \( \sin 38^\circ \)
- b) \( \cos 73^\circ \)
- c) \( \tan 40^\circ \)

Let's evaluate each trigonometric ratio:

### a) \( \sin 38^\circ \)
Using a calculator or trigonometric tables:
\[
\sin 38^\circ \approx 0.6157
\]

### b) \( \cos 73^\circ \)
\[
\cos 73^\circ \approx 0.2924
\]

### c) \( \tan 40^\circ \)
\[
\tan 40^\circ \approx 0.8391
\]

These are the approximate values of the trigonometric ratios for the given angles.

Would you like more details on how these values are calculated, or any clarifications?

Here are 5 follow-up questions to deepen your understanding:
1. How are the sine, cosine, and tangent functions defined in a right triangle?
2. What is the complementary relationship between \( \sin \theta \) and \( \cos(90^\circ - \theta) \)?
3. Can you explain how the unit circle relates to these trigonometric functions?
4. How would you find \( \sec 38^\circ \) or \( \csc 73^\circ \) based on the values given?
5. What are the reciprocal identities for sine, cosine, and tangent?

**Tip**: Always ensure your calculator is set to degrees when calculating trigonometric ratios for angles given in degrees.
