**Title:** Vector Projections and Parallelogram Completion

**Content:**

**D. Exercise: Complete the parallelogram below. Determine the length of each side. Show that \( \text{Proj}_{\mathbf{N}} \mathbf{a} + \text{Proj}_{\mathbf{T}} \mathbf{a} = \mathbf{a} \).**

**Diagram Explanation:**

The given diagram illustrates a vector analysis involving projections. Key elements of the diagram include:

- **Vectors:**
  - \( \mathbf{T} \) and \( \mathbf{N} \) are shown as red arrows representing two different vectors.
  - \( \mathbf{a} \) is a green arrow representing another vector.
  
- **Axes:**
  - The graph includes labeled axes with degrees marked from 10 to 90, allowing for angular reference.
  
- **Curves and Components:**
  - A blue curve is displayed, likely representing a path or a function graph.
  - Dotted red and black lines indicate potential components or pathways of the vector projection.

**Objective:**

The task is to complete the parallelogram formed by these vectors and verify that the sum of the projections of vector \( \mathbf{a} \) onto vectors \( \mathbf{N} \) and \( \mathbf{T} \) equals the vector \( \mathbf{a} \) itself. This involves calculating the magnitudes using projection formulas and demonstrating the vector addition graphically within the diagram.
