Answer:

130°, 50°

Step-by-step explanation:

a+b =180 ....(1)

& a-b = 80.....(2)

from (2)

a = 80+b

from (1)

a+b =180

80+b+b = 180

2b+80 = 180

b = 100/2

b= 50°

from (1)

a+b = 180

a+50 = 180

a= 130°

Answer:

a=130 b=50

Step-by-step explanation:

given

a-b=80 .. 1

a+b=180(linear pair) ..2

solve 1& 2

a+b=180

-a+b=80

b=50

solve b in 2

a+50=180

a=180-50

a=130
