### Polar Coordinates Distance Calculation

**Problem Statement:**
Two plane polar coordinates have the coordinates \((2.2, 48.3^\circ)\) and \((4.6, 10.5^\circ)\). Calculate the distance between them. Round your answer to 1 decimal place.

**Detailed Explanation:**

In polar coordinates, a point in the plane is represented as \((r, \theta)\), where:

- \(r\) is the radial distance from the origin.
- \(\theta\) is the angular coordinate (or angle) in degrees.

To find the distance \(d\) between two points \((r_1, \theta_1)\) and \((r_2, \theta_2)\) in polar coordinates, you can use the formula:

\[ d = \sqrt{r_1^2 + r_2^2 - 2 r_1 r_2 \cos(\theta_2 - \theta_1)} \]

1. For the coordinates \((r_1, \theta_1) = (2.2, 48.3^\circ)\):
   - \(r_1 = 2.2\)
   - \(\theta_1 = 48.3^\circ\)

2. For the coordinates \((r_2, \theta_2) = (4.6, 10.5^\circ)\):
   - \(r_2 = 4.6\)
   - \(\theta_2 = 10.5^\circ\)

Convert the angular difference \((\theta_2 - \theta_1)\) to radians if necessary, or use the cosine of the difference directly in degrees:

\[ \cos((\theta_2 - \theta_1)^\circ) = \cos(10.5^\circ - 48.3^\circ) \]

Then, substitute the values into the formula to compute the distance \(d\).

**Note for Educational Websites:**
- Ensure that students understand how to convert between degrees and radians if needed.
- Explain the cosine function and its significance in the formula.
- Provide step-by-step calculations and intermediate results to enhance understanding.

Remember to use appropriate mathematical notation and clarify each step for better readability and comprehension.
