Sine rule

Sine rule is used to show the relationship between the sides of a triangle as well as their opposite angles. It is given by:

[tex]\frac{a}{sin(A)}= \frac{b}{sin(B)}=\frac{c}{sin(C)}[/tex]

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:

[tex]\frac{c}{sin(C)} =\frac{b}{sin(B)} \\\\\frac{27}{sin(27)}=\frac{b}{sin(29)} \\\\b=28.83\ miles \\[/tex]

Station A is at a distance of 28.83 miles from the storm
