Answer:
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes.
The exemplar equation has slope 
9x - 3y = 18
     - 3y = -9x + 18
         y = 3x - 6
m = 3
so perpendicular slope will be -1/3
D has such a slope
3y = -x + 1
  y = (-1/3)x + 1/3

My guess is that there is 5 angles and 5 sides... because i divided 10 in half 
likeee this 
10 ÷ 2 = 5 
and bam we have our answer
