Answer:

1440°

Step-by-step explanation:

Sum of exterior angles = 360

One exterior angle = 360 ÷ 10

                                 = 36°

Exterior angle + interior angle = 180

Interior angle = 180 - 36

                      = 144°

Sum of interior angles = 144° × 10

                                     = 1440°
