Answer 2

Answer:

$130$°

Step-by-step explanation:

   ∠$FAD$ = $140$°

   ∠$ABC$ = $140$°

   ∠$BCE$ = $130$°

   ∠$CDA$ = $x$

⇒ ∠$DAB$ = $180 - 140$ = $40$°          (Angles in a straight line)

⇒ ∠$BCD = 180 - 130 = 50$°        (Angles in a straight line)

We know that sum of angles in a quadrilateral = $360$°

⇒ ∠$ABC$ + ∠$BCD$ + ∠$CDA$ + ∠$DAB$ = $360$°

⇒ $140 + 50 + x + 40 = 360$°

⇒ $230 + x = 360$°

⇒ $x = 360 - 230$

⇒ $x = 130$°
