A rectangle with sides parallel to the coordinate axes is shown in the figure. Vector A goes from the origin to the upper left corner of the rectangle, and vector B goes from the origin to the lower right corner. A = 8.00 m at 50.0 from the x-axis, and B = 12.0 m at 27.0 from the x-axis. Two vectors and a rectangle are plotted in the first quadrant of an x y plane. Vector A starts at the origin and ends at the upper left corner of the rectangle. Vector B starts at the origin and ends at the lower right corner of the rectangle. (a) Calculate the rectangle's perimeter (in m). m (b) What are the magnitude (in m) and direction (in degrees counterclockwise from the x-axis) of a vector from the origin to rectangle's upper right corner? m at counterclockwise from the x-axis
