I will be using the Law of cosine
a2=b2+c2-2bc*cos(deg)
Example: would be if a car in the dessert was traveling 4.3m one way then turn at 30 degrees and went to 7.2m another direction.
If side b = 4.3m at an angle of 30 degrees and another side c =7.2m we use the law of cosine as such.
a2=4.32+7.22-2(4.3)(7.2)*cos(30)
a2=18.49+51.84-53.6243
a2=16.7057
once your answer you can now solve for side a. to do that you would need to take the square root of it.
a2=16.7057 will now be
which should give us 4.08726
round to 4.1m
I think this would be how cell phones are tracked too.
