*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.*
