Question

find the value of angle a,b,c, if line 1 and line m are parallel lines pls tell step by step​

Answer 1

Answer:

b + 130 = 180 (linear pair axiom)

therefore b=50

a=50 as b=50 and using the vertically opposite angle we can find 'a' as 'a' is alternate interior angle to that angle.

also c+a=180 (linear pair axiom)

therefore c+50=180

therefore c=130
