Answer:

1: a= 55

b= 125

2: b = 73

c = 107

Explanation:

1: let c

c = 125 ( being alternate angle)

a+c = 180 (linear pair)

a = 180 - 125

a = 55

b=c=125 (being vertically opposite angle)

--------------------------------------------------------------------------------------------------

2: let a

42+65+a = 180 (sum of angle of a triangle)

a = 73

b = 73 (being vertically opposite angle)

b+c = 180 (being linear pair)

c = 180-73

c = 107
