Let's analyze the image and solve the problems given.

### Understanding the Diagram
The diagram shows two intersecting lines forming multiple angles. The angles are labeled with numbers (2, 5, 6, 8, etc.). The problem provides different conditions to find the measures of certain angles.

### Solution for Part (a)
- **Given:** \(\angle 6 = 58^\circ\)
- **To Find:** \(\angle 2, \angle 5, \angle 8\)

#### Step-by-Step Solution for (a)

1. **Finding \(\angle 5\):**  
   \(\angle 5\) and \(\angle 6\) are vertically opposite angles. Vertically opposite angles are equal, so:  
   \[
   \angle 5 = \angle 6 = 58^\circ
   \]

2. **Finding \(\angle 8\):**  
   \(\angle 6\) and \(\angle 8\) are supplementary angles because they are on a straight line (linear pair). Thus:  
   \[
   \angle 6 + \angle 8 = 180^\circ  
   \]
   Substituting \(\angle 6 = 58^\circ\), we get:  
   \[
   58^\circ + \angle 8 = 180^\circ  
   \]
   \[
   \angle 8 = 180^\circ - 58^\circ = 122^\circ  
   \]

3. **Finding \(\angle 2\):**  
   \(\angle 2\) and \(\angle 8\) are vertically opposite angles, so they are equal:  
   \[
   \angle 2 = \angle 8 = 122^\circ  
   \]

### Solution for Part (b)
- **Given:** \(\angle 8 = 144^\circ\)
- **To Find:** \(\angle 2, \angle 5, \angle 6\)

#### Step-by-Step Solution for (b)

1. **Finding \(\angle 2\):**  
   \(\angle 2\) and \(\angle 8\) are vertically opposite angles. Thus:  
   \[
   \angle 2 = \angle 8 = 144^\circ  
   \]

2. **Finding \(\angle 6\):**  
   \(\angle 6\) and \(\angle 8\) are supplementary angles (linear pair). Thus:  
   \[
   \angle 6 + \angle 8 = 180^\circ  
   \]
   Substituting \(\angle 8 = 144^\circ\), we get:  
   \[
   \angle 6 = 180^\circ - 144^\circ = 36^\circ  
   \]

3. **Finding \(\angle 5\):**  
   \(\angle 5\) and \(\angle 6\) are vertically opposite angles, so:  
   \[
   \angle 5 = \angle 6 = 36^\circ  
   \]

### Final Answers:
- **Part (a):**  
  - \(\angle 2 = 122^\circ\)  
  - \(\angle 5 = 58^\circ\)  
  - \(\angle 8 = 122^\circ\)

- **Part (b):**  
  - \(\angle 2 = 144^\circ\)  
  - \(\angle 5 = 36^\circ\)  
  - \(\angle 6 = 36^\circ\)
