Question

I need help with this assignment 

### Focus: What are the trigonometric ratios?

#### Learning Objective:
- I will be able to find the missing side lengths of a right triangle by using trigonometric ratios.

#### Write the value for each trigonometric ratio:

1. **tan A**
   - Diagram: A right triangle with legs labeled as follows: AC = 34, AB = 16, and BC = 30.
2. **cos C**
   - Diagram: A right triangle with legs labeled as follows: AC = 15, AB = 9, and BC = 12.
3. **sin Z**
   - Diagram: A right triangle with legs labeled as follows: XZ = 20, ZY = 16, and YX = 12.
4. **sin C**
   - Diagram: A right triangle with legs labeled as follows: AC = 50, AB = 40, and BC = 30.

##### Graphs/Diagrams Explanation:
1. **tan A Diagram**:
    - Triangle with one of the angles labeled as \( A \).
    - The opposite side of angle \( A \) is 30 units, the adjacent side is 16 units, and the hypotenuse is 34 units.
      
2. **cos C Diagram**:
    - Triangle with one of the angles labeled as \( C \).
    - The adjacent side to angle \( C \) is 12 units, the opposite side is 9 units, and the hypotenuse is 15 units.
      
3. **sin Z Diagram**:
    - Triangle with one of the angles labeled as \( Z \).
    - The side opposite of angle \( Z \) is 16 units, the adjacent side is 12 units, and the hypotenuse is 20 units.
      
4. **sin C Diagram**:
    - Triangle with one of the angles labeled as \( C \).
    - The side opposite to angle \( C \) is 30 units, the adjacent side is 40 units, and the hypotenuse is 50 units.

##### Note:
- Students are encouraged to draw or write on the provided slides to solve for the values of each trigonometric ratio.

### Find the length of the missing side:

#### Problem 5:
A right triangle is presented with the following details:
- One angle is 38°.
- The length of the side adjacent to the 38° angle is \( x \).
- The length of the hypotenuse is 20 units.

Illustration:
```
   /|
x / | 20
 /  | 
/___|
38°
```

#### Problem 6:
A right triangle is presented with the following details:
- One angle is 63°.
- The length of the side opposite the 63° angle is 23 units.
- The length of the hypotenuse is \( x \).

Illustration:
```
   /|
23/ | x
 /  |
/___|
63°
```
