Question

7. Given / || m, find the value of the unknown angles in each of the following figures.
В B.​

Answer 1

Answer:

In the given line t is the transversal.

And l || m.

Step-by-step explanation:

If l || m, 2x + x = 180° ( Angles on same side of transversal).

= 2x + x → 180°

= 3x → 180°

$= x = \frac{180}{3} = 60$

Therefore, x = 60°.......

→ Now 2x = 60 × 2 → 120°

Answer 2

Answer:

x= 60.........is the answer...........
