Answer:

The distance from the Colonel to the campfire is 353 feet.

The distance from the Campfire to Sarge is approximately 395 feet.

Step-by-step explanation:

Please see the attached image for the pictorial representation of the problem.

We are to determine the length AB and BC in the diagram.

The triangle formed is an Isosceles Triangle, therefore:

The distance from the colonel to the campfire is 353 feet.

Using Law of Sines

[tex]\dfrac{a}{sinA} =\dfrac{b}{sinB} \\\dfrac{a}{sin68} =\dfrac{353}{sin56} \\aXsin56=353Xsin68\\a=(353Xsin68)\div sin 56\\a=394.79 feet[/tex]

The distance from the Campfire to Sarge is approximately 395 feet.
