Answer 1

Answer:

In given figure, l parallel to n and q is a transversal.

∴6a=120

o

... Corresponding angle

⇒a=

6

120

o

=20

o

Now, p parallel to q and n is a transversal.

∴4c=120

o

... Corresponding angle

⇒c=

4

120

o

=30

o

... Equation 1

Also, m parallel to n and p is a transversal.

∴4c=3b ... Corresponding angle

⇒4×30

o

=3b ... from Equation 1

⇒b=

3

120

o

=40

o

Therefore, a=20

o

, b=40

o

and c=30

o

Answer 2

Answer:

the lines p and q are parallel

because opposite angle of 40 is 40

and then sum of the one side internal angles

(140+40==180

so the lines are parallel
