Answer:

1440

Step-by-step explanation:

decagon = 10 sides

                  7 diagonals

an angle of a polygon= [n-2]multiplied by 180

                                       ----------------------------------

                                                       n

   =  [10-2] multiblied by 180,divided by n

   = 8 muliplied by 180 ,divided by n

   = 1440 divided by n

   =1440 divided by 10

   = 144

   sum of all the angles = 144 multiplied by 10

                      =1440
