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
228-12.4%= 199.728
199.728 rounded to the nearest tenth is *199.7*
33 because 6x5=30 then plus 3 equals 33
