### Using Triangles to Find Side Lengths

Using the triangles below, answer the following correctly.

#### Triangle A
- A right-angled triangle with sides labeled as follows:
  - One leg is 6 units long.
  - The hypotenuse is marked as \( y \).
  - The other leg is marked as \( x \) and adjacent to the 45-degree angle.

```

     | \
     |  \
     |   \ y
     |    \
     |     \
     |      \
     |-------\
        x     45°
```

#### Triangle B
- A right-angled triangle with sides labeled as follows:
  - One leg is \( 14\sqrt{3} \) units long.
  - The hypotenuse is marked as \( y \).
  - The shorter leg is marked as \( x \) and adjacent to the 30-degree angle.

```
         y
        |\
        | \
        |  \
        |   \
30°     |    \
        |     \ 
        |------\
       x  14√3
```

### Calculations

For **Triangle A**, to help find the sides, use the ratio for a 45-45-90 triangle: \( 1 : 1 : \sqrt{2} \).

Then,
- \( x = 6\sqrt{2} \)
- \( y = 6 \)

For **Triangle B**, to help find the sides, use the ratio for a 30-60-90 triangle: \( 1 : \sqrt{3} : 2 \).

Then,
- \( x = 7 \)
- \( y = 7\sqrt{3} \)

### Key Concepts

- **45-45-90 Triangle**: This is an isosceles right triangle where the legs are equal, and the hypotenuse is the leg length multiplied by \( \sqrt{2} \).
- **30-60-90 Triangle**: This is a special right triangle where the shortest leg is opposite the 30-degree angle, the hypotenuse is twice the length of the shortest leg, and the other leg is the shortest leg multiplied by \( \sqrt{3} \).
