Answer 2

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°
