∠DOC is the average of the given angle values,
(170° +44°)/2 = 107°
∠DOB is the supplement to that,
180° -107° = 73°
The appropriate choice is
B) 73°
This means that we have to didvide the 12 inches wide side into 3 parts: one of 3.5 inches, and two other, of equal size (the margins).
the margins together will have (12-3.5=8,5) inches, which means that each of them will hace half of this: so we have to divide 8.5 into 2.
this is: :
8.5/2=4.25
so he has to to put it 4.25 inches from each side.
(8/9)^2= 8/9 * 8/9
8*8=64
9*9=81
Final answer: 64/81
