Question

Write the equation of line l and m as shown in figure ,Also name the line which is represented by x=0​

Answer 1

Answer:

x=140

Step-by-step explanation:

40

∘

+u=180

∘

⇒u=140

∘

ω+u=180

∘

⇒ω=180°−u

=40°

∠z=70°(vertically opposite angles)

∠y+∠z=180°

⇒∠y=180°−∠z

180°−70°

=110°

⇒ω+x=180

∘

∴x=140
