  • 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°
