Question

B А D . С AB is parallel to AC.
​

Answer 1

$\huge\mathfrak\pink{Answer}$

As per the diagram, lines CD∣∣EF and CE is transveral.

We know that sum of interior angles is equal to 180 o

∠ECD+∠CEF=180 o

∠ECD+130 o=180 o

∠ECD=180−130 o

∠ECD=50 o

As per the diagram, lines AB∣∣CD and CA is transveral.

We know that alternate angles are equal.

Answer 2

$\huge\mathtt\pink{♡Answer♡}$

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 o=180°

∠ECD=180−130°

∠ECD=50°

As per the diagram, lines AB∣∣CD and CA is transveral.

We know that alternate angles are equal.

hope it helps ♡

plss make me as brainliest.
