Question

2) In the figure line 1 Il line m, line p is the transversal. If r = 20° then find ca and angel b.​

Answer 1

Answer:

Step-by-step explanation:

Given:l∥m

sum of the interior angles on the same side of transversal is 180  

∘

 

b+52  

∘

=180  

∘

 

⇒b=180  

∘

−52  

∘

=128  

∘

 

And a=52  

∘

 

∴a=52  

∘

,b=128
