Step-by-step explanation:
AB∣∣CD and AE∣∣CF, ∠FCG=90
o
and ∠BAC=120
o
line AB ∣∣ line CD
∴ ∠BAC and ∠ACD are supplementary angles.
Sum of supplementary angles is 180
0
∴∠BAC+∠ACD=180
0
∴120

+x=180

∴x=60

Also,
∠DCA+∠ACF+∠FCG=180

line AE ∣∣ line CF
∴ ∠EAC and ∠ACF are supplementary angles.
Sum of supplementary angles is 180
0
∴∠EAC+∠ACF=180

∴z+y=180
