Answer 2

Step-by-step explanation:

let angle 1 be x

angle 2 be y

sum of all angles = 180

so 180 = x+y+ third angle

180= 80 + third angle

third angle = 100

x+y=80

x=80-y (i)

x-y = 20

80-y-y = 20 (putting x=80-y , from (i) )

80-2y=20

2y = 60

y=30 (ii)

as x+y = 80

x+30 = 80 ... from (ii)

x=50

all angles are , 50, 30, 100
