1. The problem statement, all variables and given/known data A basketball player runs down the court, following the path indicated by the vectors A,B, and C in the figure. The magnitudes of these three vectors are 10, 20 and 7 m . Assume the positive x axis is directed to the right. There is a 45degree angle outside of where A and B meet, and there is a 30degree angle outside of where B and C meet. I have found what Dx and Dy are. Dx and Dy are 20m, and 0m. In order to find the degree of the equation you would have to take the tan^-1(Dy/Dx). My question is, how do you solve this when Dy = 0? The answer is not 0 degrees, I know this for a fact. Thanks for all the help!
