This is parallelogram so
8=2x
X=4
Or
3x=12
So again we will find x=4
The towns population will be 2,720 in 2005
The 3 inside angles need to equal 180.
Subtract E from 180 to find the sum of the other two angles:
180 - 104 = 76
Now because EF ≅ DE , angle D and F would be the same so divide 76 by 2
Angle D = 38
That's simplied already, unless they want a decimal then it's .6 or something
