You can put this solution on YOUR website! Town B is 10kms. east of town A, town C is 7.5 kms. N53°12’W of town A. How far is town C from town B? How does town C bear from town A?
------------
You have 2 sides and the included angle.
Use the Cosine Law to find the 3rd side.
============
"How does town C bear from town A?" is non-sensical. Town C does not bear from town A.

Plus, this "N53°12’W" is just irritating. Why not use either compass headings or the angle with the positive x-axis?
