(D) 30°

1. A || B & l is transversal.

$\huge\sf \green{\underline{\red{\underline{\blue{\underline{\orange{To \: Find :-}}}}}}}$

• Find x.

$\huge\sf \green{\underline{\red{\underline{\blue{\underline{\orange{Solution :-}}}}}}}$

→ p = 2x [Vertically opposite angle (V.O.A.)]

So,

→ 4x + p = 180° [Sum of interior angles]

Therefore,

→ $4x + 2x = 180°$

→ $6x = 180°$

→ $x = \frac{\cancel{180}}{\cancel6}$

→ $\boxed{x = 30°}$

Hence,

Option (D) is the correct.
