Answer 2

Step-by-step explanation:

First figure:

We see l ║m, t is transversal.

110° = y° [See figure]

• [∵ Corresponding angles are equal]

Now,

y° + x° = 180°

• [∵ Linear pair]

⇒ 110° + x° = 180°

∴ x° = 70°

Second figure:

We see l ║m.

Now,

x + 2x = 180°

• [∵ Interior Angles are supplementary]

⇒ 3x = 180°

⇒ x = 180°/3

∴ x = 60°
