Decagon ABCDEFGHIJ is rotated centered at G by an angle of x, and moves point D to J. Find x if it is less than 180 degrees.

Each interior angle of the decagon is ((n-2) * 180)/n= 144 degrees. So if D is shifted over to J which is 6 or 4 angles over, x= 144 * 6 or 144 * 4= 864 or 576 degrees. Neither angle is less than 180 degrees, so I'm not sure if the problem is correct.

so basically since its not less than 180 degrees, you're wrong, which is why you're correct on your statement afterwards. great job
