How do you do this and what is the answer
Talja [164]
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
