In order to have a closed geometric figure composed of straight lines (Figure 1), the angles in the figure must add to where n is the number of sides. Figure 1 Write a program that uses a menu so that a user can choose one of the following: Triangle Square Pentagon Hexagon Hint: Use the menu selection to define the value of n via a switch/case structure; then use n to calculate the sum of the interior angles in the figure. Output the total sum of angles
