Từ O kẻ Oz //a ( kéo dài sang phía bên phải nha bn )

Mà a//b => Oz//a//b

a//Oz => \(\widehat{A}=\widehat{AOz}=40^o\)

Oz//b => góc zOB = góc B = 30 độ

Ta có : góc AOB = góc AOz + góc zOB ( 2 góc kề nhau )

=> góc AOB = 40 độ + 30 độ

góc AOB = 70 độ

Vậy góc AOB = 70 độ

Bạn tự vẽ hình theo diễn đạt của mình nha! Vẽ cx dễ thôi.

Vẽ trong góc AOB tia Oc sao cho OC//a

\(\Rightarrow\widehat{aAO}=\widehat{AOC}\) (2 góc so le trong)

\(\Rightarrow\widehat{AOC}=40^o\)

Vì OC// a, b//a nên OC//b

\(\Rightarrow\widehat{BOC}=\widehat{OBb}\)

\(\Rightarrow\widehat{BOC}=30^o\)

Vì tia OC nằm giữa 2 tia OA và OB nên

\(\widehat{AOC}+\widehat{BOC}=\widehat{AOB}\)

\(\Rightarrow40^o+30^o=\widehat{AOB}\)

\(\Rightarrow\widehat{AOB}=70^o\)

Vậy \(\widehat{AOB}=70^o\)

Từ O kẻ c//a//b

Ta có a//b//c

AOB = 180-(A+B)

=180-(40+30)

=180-70

=110
