- To Find The Value of "x" , we need to find ∠1, ∠2, ∠3 respectively
___________________________________
∠1 + 127° = 180° (Linear Pair)
⇒ ∠1 + 127° - 127° = 180° - 127°
⇒ ∠1 = 53°
___________________________________
∠2 + 133° = 180° (Linear Pair)
⇒ ∠2 + 133° - 133° = 180° - 133°
⇒ ∠2 = 47°
___________________________________
∠1 + ∠2 + ∠3 = 180° (Angle Sum Property)
⇒ 53° + 47° + ∠3 = 180°
⇒ 100° + ∠3 = 180°
⇒ 100° + ∠3 - 100° = 180° - 100°
⇒ ∠3 = 80°
_____________________________________________________
7x + 3x = ∠3 (Alternate interior angles)
⇒ 10x = 180°
⇒ 10x/10 = 180°/10
⇒ x = 18°
