In the given question;

AB//CD

_____________________________________________________

Angle DAE + Angle AEF = 180,

Because DAE and AEF are co-interior angles.

let Angle AEF be x. then,

120 + x = 180

x = 60

Angle AEF = 60 degrees.

_____________________________________________________

Angle DCE + Angle FEC = 180

Because DCE and FEC are co-interior angles.

let Angle FCE be x. then,

120 +  x = 180

x = 60

Angle FCE = 60 degrees

_____________________________________________________

Angle AEC = Angle AEF + Angle FCE

 = 60 + 60

 = 120 \: degrees

Hope it helps.
