### Triangles and Trigonometry Problems

**Problem Descriptions:**

**17) Triangle:**
- A right triangle with:
  - One angle measuring \(30^\circ\).
  - The side opposite the \(30^\circ\) angle is labeled \(4\sqrt{3}\).
  - Hypotenuse is labeled \(y\).
  - Other leg is labeled \(x\).

**18) Triangle:**
- A right triangle with:
  - One angle measuring \(45^\circ\).
  - Hypotenuse labeled as \(6\sqrt{2}\).
  - Legs labeled \(x\) and \(y\).

**19) Triangle:**
- A right triangle with:
  - One angle measuring \(45^\circ\).
  - Side adjacent to the \(45^\circ\) angle labeled \(3\sqrt{3}\).
  - Legs labeled \(u\) and \(v\).

**20) Triangle:**
- A right triangle with:
  - One angle measuring \(60^\circ\).
  - Opposite side to the \(60^\circ\) angle labeled as \(6\).
  - Other leg labeled \(n\).
  - Hypotenuse labeled \(m\).

**Equations for Solutions:**

Fill in the missing sides for each triangle using trigonometric ratios or special right triangle properties.

- **17)** \(x = \_\_\_\_\_\_\_\_\_\)
     \(y = \_\_\_\_\_\_\_\_\_\)

- **18)** \(x = \_\_\_\_\_\_\_\_\_\)
     \(y = \_\_\_\_\_\_\_\_\_\)

- **19)** \(u = \_\_\_\_\_\_\_\_\_\)
     \(v = \_\_\_\_\_\_\_\_\_\)

- **20)** \(m = \_\_\_\_\_\_\_\_\_\)
     \(n = \_\_\_\_\_\_\_\_\_\)

**Instructions:**
- Calculate the missing side lengths using the properties of right triangles.
- Use known trigonometric identities and values for \(30^\circ\), \(45^\circ\), and \(60^\circ\) angles.
