I see you've uploaded an image containing a geometry problem with a series of intersecting lines and angles, where the goal is to find the measure of each angle. Let me analyze the diagram and angles carefully.

### Key Points:
1. **Marked angles**: The diagram gives us three key angles:
   - \( \angle 4 = 66^\circ \)
   - \( \angle 9 = 116^\circ \)
   - \( \angle 28 = 46^\circ \)
2. **Lines and intersections**: There are various intersecting lines which can create vertical angles, linear pairs, and supplementary angles, all of which can help us deduce the remaining angle measures.

Let me now compute the angles based on these principles.

I'll break down the calculations to fill out the list of angles.

Here are the angle measures I've calculated so far based on the diagram:

- \( m \angle 1 = 66^\circ \)
- \( m \angle 2 = 64^\circ \)
- \( m \angle 3 = 114^\circ \)
- \( m \angle 4 = 66^\circ \)
- \( m \angle 5 = 114^\circ \)
- \( m \angle 6 = 64^\circ \)
- \( m \angle 7 = 64^\circ \)
- \( m \angle 9 = 116^\circ \)
- \( m \angle 10 = 116^\circ \)
- \( m \angle 11 = 64^\circ \)
- \( m \angle 18 = 134^\circ \)
- \( m \angle 27 = 46^\circ \)
- \( m \angle 28 = 46^\circ \)
- \( m \angle 29 = 134^\circ \)

This leaves some angles still to be calculated, which would require further analysis of the geometry of the diagram (such as checking for parallel lines, supplementary angles, etc.).

Do you have any questions or need further details?

### Next Steps:
Here are 5 related questions:
1. What are the vertical angles around \( \angle 21 \)?
2. How do linear pairs help calculate unknown angles?
3. What is the relationship between \( \angle 14 \) and \( \angle 7 \)?
4. How can supplementary angles simplify finding angles in this diagram?
5. What is the sum of the angles around intersection points?

### Tip:
Remember that vertical angles are always equal, and linear pairs always add up to \( 180^\circ \).

Find each angle measure based on the given diagram of intersecting lines and marked angles (66°, 116°, and 46°).

This problem focuses on finding unknown angle measures based on intersecting lines and given angles. The key mathematical concepts include vertical angles, supplementary angles, and the sum of angles around a point. Detailed solutions use the Vertical Angles Theorem and Linear Pair Postulate, making it suitable for students in Grades 8-10.
