What is the sun of the interior angles in the figure shown? - 210
- 510
- 720
- 1080

720°

Step-by-step explanation:

(180° x 6) - 360° = 720°

checking:

(right side) 2 angles 90° = 180°

(left side) 0ne pair of supplementary angles = 180°

(center) One angle  180° + ?°

             One angle  180° - ?°

             Equals 2 angles  180°

             Total = 720°

to determine the unit cost your would divide the total cost by the number sold.
