We know opposite angles in the parallelogram is congruent:
let x to be the unknown angle:
360=2(110)+2x
360=220+2x
140=2x
x=70
ECF is also 110 because of parallel lines and corresponding angles:
110+x+y=180
110+30+y=180
y=40
so DAE is 40

(91 oil changes)/(7 days) = 13 oil changes/day
Since we want to know the number of oil changes in 11 days, we multiply the unit rate by 11 days.
13 oil changes/day * 11 days = 143 oil changes
