Calc. Angle between radius vector point and positive x axis? What does that mean??? 1. The problem statement, all variables and given/known data The cartesian coordinates of a point in the xy plane are x = −8.96 m, y = −1.75 m. Calculate the angle between the radius- vector of the point and the positive x axis (measured counterclockwise from the positive x axis, within the limits of −180◦ to +180◦). Answer in units of ◦. 2. Relevant equations arctan of (y/x) = angle/degree 3. The attempt at a solution I did arctan of y/x = 11.051 incorrect.... I did the arctan of y/x + 180 and got 191.05 incorrect... I did that same method - 180 = 168 ish still inccorrect... then I did arctan of x/y + 180= 258 ish and still wrong.. any ideas what this question is asking for? or what the correct answer is??
