**Title: Vector Magnitude and Angle Calculation**

**Objective:**
Approximate the magnitude of the vector and the angle \( \theta \), in the range \( 0^\circ \leq \theta < 360^\circ \), that the vector makes with the positive x-axis. Round your answers to the nearest tenth.

**Given Vector:**
\[ \mathbf{W} = \sqrt{15} \mathbf{i} - 7 \mathbf{j} \]

**Instructions:**

1. Calculate the magnitude of the vector \( |\mathbf{W}| \) using the formula:
   \[ |\mathbf{W}| = \sqrt{( \text{component of } \mathbf{i} )^2 + (\text{component of } \mathbf{j} )^2} \]
   
2. Determine the angle \( \theta \) that the vector makes with the positive x-axis using the inverse tangent function:
   \[ \theta = \tan^{-1} \left( \frac{\text{component of } \mathbf{j}}{\text{component of } \mathbf{i}} \right) \]
   
**Solution:**

- **Magnitude:**
  The field for the magnitude \( |\mathbf{W}| \) is correctly filled with 8.

- **Angle:**
  The field for the angle \( \theta \) is currently empty and marked incorrect.

**Steps to input the answer:**

1. Calculate and verify the magnitude using the provided formula.
2. Use the arctangent function to find the angle \( \theta \).
3. Ensure to adjust the angle if necessary, depending on the quadrant in which the vector lies.
4. Enter your answers in the respective fields and click "Submit Answer."

**Output:**
The interface contains a section for the submission of the calculated values. A green checkmark and a red cross are beside the fields, indicating the correctness of the entered magnitude and the incorrectness of the angle, respectively. 

Remember to double-check your calculations to ensure accurate results.
