Answer:
Town C is approximately 58.356 kilometers from town A.
Step-by-step explanation:
According to the statement, we understand that tourist travels from town A to town B (50 kilometers) at a direction of 80º west of north and from town B to town C (40 kilometers) at a direction of 20º east of north. Vectorially speaking, the resultant from town A to town C is described by the following formula:
![\vec r = (-35.560,46.270)\,[km]](https://tex.z-dn.net/?f=%5Cvec%20r%20%3D%20%28-35.560%2C46.270%29%5C%2C%5Bkm%5D)
The distance from town A to town C is the magnitude of vector reported above, which is now calculated by Pythagorean Theorem:
Town C is approximately 58.356 kilometers from town A.

Answer:
Danny did not reverse the symbol.
Hence, the correct answer is: 
Step-by-step explanation:
Given the inequality
We know that when we multiply both sides by -1, the 'inequality' gets reverse.
i.e.
Divide both sides by 8
Therefore, Danny did not reverse the symbol.
Hence, the correct answer is:
