Answer 2

Step-by-step explanation:

a)103 + 7a = 180( cd is a straight line)

7a = 180 - 103

7a = 77

a = 11

2b + 13 = 103 ( vertically opposite angle )

2b = 103 - 13

2b = 90

b = 45

c )7f + 5 = 2f + 35(vertically opposite angle )

7f - 2f = 35 - 5

5f = 30

f = 6

5g + 18 = 2f + 35( ab is a straight line)

5g = 2*6 + 35 - 18

5g = 12 + 35 - 18

5g = 47 - 18

5g = 29

g = 5. 8
