Question

Please can anyone help me out fast

Answer 1

Answer:

its simple

Step-by-step explanation:

first entend the Ef backwords then its angle will be 57 so two lines having same angle will be parallel

Answer 2

$\small\fcolorbox{red}{white}{To prove :-}$

AB || EF

$\small\fcolorbox{red}{white}{Proof :-}$

<BAC = 57°

<DCA = (22+35) = 57°

Hence, <BAC = <DCA

Since, Alternate interior angles are equal .

So AB || CD ________(i)

Now,

<ECD + <CEF = 145° + 35° = 180°

Since, co-interior angles make sum of 180°

So, CD || EF ________(ii)

From (i) and (ii)

AB || EF proved.
