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
