pls check the pic and answer pleasee

Answer 1

Answer:

60+20+1=180(angle sum property)

80+<1=180

<1=180-80

<1=100

60+20=<2(exterior angle property)

<2=80

I hope my answer helps you☺☺

Answer 2

Answer:

angle 1 =100

angle 2 =80

Step-by-step explanation:

let us take angle 1 as "X"

60⁰+20⁰+x=180

80⁰+X=180

X=180-80

X=100

therefore, angle 1=100⁰

let us take angle 2 as "y"

angle 1 + angle 2 = 180 (since linear pair )

100⁰+y =180

y=180-100

Y=80

therefore, angle 2=80⁰
