Question

In the adjoining figure if l || m and t is transversal, find the value of x.
t
60°
​

Answer 1

Answer:

130 is the right answer.

Step-by-step explanation:

∠1+∠2=180

∘

(Adjacent angles on a straight line are supplementary)

⇒50

∘

+∠2=180

∘

⇒∠2=180

∘

−50

∘

⇒∠2=30

∘

Now l∣∣m and t is transversal

∴∠x=∠2 (Alternate angles)

⇒∠x=130
