Step-by-step explanation:
As per the diagram, lines CD∣∣EF and CE is transveral.
We know that sum of interior angles is equal to 180°
∠ECD+∠CEF=180°
∠ECD+130° =180°
∠ECD=180°−130°
∠ECD=50°
As per the diagram, lines AB∣∣CD and CA is transveral.
We know that alternate angles are equal.
∠BAC=∠ACD
∠BAC=∠ACE+∠ECD
70°=∠ACE+50°
20°=∠ACE
∴∠ACE=20°
