360°/ 5 = 72° the angles created at each panel joint.

72°/2 = 36° the two bevels needed to create the angle.

You’ll might also need to bevel the top (and bottom) edges of each side. That bevel will change depending on what angle (miter cut) you decide on for each side. More angle (obviously) will result in a greater difference in the top and bottom perimeters, as well as a need for more bevel. I don’t know how to mathematically determine what that top bevel would be. I would use a dry fit to see what angle is measured between the table and the box (perpendicular to the face of a panel) and apply that same angle to your top bevel cut.
