2,4,6,8=100degree √

1,3,5,7=80degree √

thanks for points

Answer 2

Answer:

<1= 80⁰

so, <3=80⁰ vertically opposite angle are equal

<3+<2= 180⁰ sum of linear pair is 180⁰

80⁰+<2=180⁰

<2=180⁰-80⁰

<2= 100⁰

<4=<2 vertically opposite angle are equal

<4=100⁰

<5=<1 corresponding angle are equal

<5= 80⁰

<8=<4 corresponding angle are equal

<8=100⁰

<6=<2 corresponding angle are equal

<6=100⁰

<7=<3 corresponding angle are equal

<7= 80⁰

Step-by-step explanation:

<1=80⁰

<2=100⁰

<3=80⁰

<4=100⁰

<5=80⁰

<6=100⁰

<7=80⁰

<8=100⁰
