Let's break down the problem to find the bearing of town B from Danielle:

1. Initial Bearing of Town A: Danielle is facing town A at a bearing of 300°.

2. Clockwise Turn: She turns 135° clockwise to face town B.

To find the bearing of town B, we add the 135° turn to her initial bearing (300°):

$300^\circ + 135^\circ = 435^\circ$

Since bearings are typically given in the range of 0° to 360°, we need to subtract 360° to normalize the value:

$435^\circ - 360^\circ = 75^\circ$

So, the bearing of town B from Danielle is 75°.

Would you like further details or clarification on any step? Here are five related questions you might find helpful:

1. What are bearings and how are they measured?
2. What is the difference between clockwise and counterclockwise directions in bearings?
3. How do you normalize an angle greater than 360°?
4. Can bearings ever be negative? Why or why not?
5. How would the problem change if Danielle turned counterclockwise instead?

Tip: When working with bearings, always remember they are measured clockwise from the north, and should be kept between 0° and 360°.
