To use the mirror, you should face a point about how many degrees between the sun and the object you wish to signal?

The correct answer is 45 degrees because this angle allows for optimal visibility and reflection of sunlight when using a signaling mirror. When signaling an object with a mirror, you want to ensure that the sunlight reflects off the mirror's surface and directs toward the intended target. By positioning yourself at a 45-degree angle relative to both the sun and the object you wish to signal, it enhances the chances of the reflected light reaching the target effectively. This angle creates a clear line of sight and ensures that the reflected beam is coherent and bright, making it easier for the intended recipient to see the signal.

In contrast, narrower angles such as 15 degrees or 30 degrees may not provide sufficient reflection to reach the object, while an angle of 60 degrees could decrease reflectivity and clarity, making the signal less effective. Understanding these angles is crucial for successful communication in rescue or signaling scenarios at sea.
