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
2b=100
b=50
solve b in 2
a+50=180
a=180-50
a=130
