Need help building this program with Visual Basic.

14 Two distances are required to specify the location of a point relative to an origin in two-dimensional space (Fig. P2.14): The horizontal and vertical distances (x, y) in Cartesian coordinates . The radius and angle (r, ) in radial coordinates. It is relatively straightforward to compute Cartesian coordinates (x, y) on the basis of polar coordinates (r, 0). The reverse process is not so simple. The radius can be computed by the following formula: If the coordinates lie within the first and fourth coordinates (i.e., x > 0), then a simple formula can be used to compute , 0 tan The difficulty arises for the other cases. The following table sum- marizes the possibilities: 40 50 0 /2 (a) Write a well-structured flowchart for a subroutine procedure to calculate r and as a function of x and y. Express the final results for in degrees
