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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F285e99a8-3963-4275-ae75-6889db8d01fa%2F5cb64064-401b-4b0b-99ce-96fb6a17cf52%2Foe4qd5c_processed.png&w=3840&q=75)

### 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°
```
