<h3>Sine rule</h3>
Sine rule is used to show the relationship between the sides of a triangle as well as their opposite angles. It is given by:
From the diagram:
- A = 34° + 90° = 124°
Also:
- B = 90° - 61° = 29°
Hence:
- C + A + B = 180°
- C + 29 + 124 = 180
- C = 27°
b = distance station A from the storm, c = AB = 27 miles
Using sine rule:
Station A is at a distance of 28.83 miles from the storm
