### Trigonometric Problem Set

#### Problem Statement
Using the following triangle with labeled angles and sides, find the following values with the given conditions:

**Diagram:**  
A right triangle with vertices labelled as A, B, and C.  
- Angle \( A \) is at vertex A.  
- Side \( a \) is the side opposite to angle \( A \).  
- Side \( b \) is the side adjacent to angle \( A \).  
- Side \( c \) is the hypotenuse.  

Illustration:

```
      B
     /|
    / |
  c/  | a
  /   |
 /____|
A      C
    b
```

#### Part A
**Given**: A = \(\frac{\pi}{3}\), c = 4

1. **Find:**
    - (a) \( b \)=
    - (b) \( B \) =  (the angle)

#### Part B
**Given**: B = 30°, a = 7

1. **Find:**
    - (a) \( b \)=
    - (b) \( c \)=

#### Part C
**Given**: A = \(\frac{\pi}{4}\), c = 20

1. **Find:**
    - (a) \( b \)=
    - (b) \( \csc(B) \)=
    - (c) \( \sin^2(A) + \sin^2(B) \)=

*(hint: Express B in terms of A)*
