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 \(\widehat{AOB}=70^o\)
bạn thử hỏi mạng nhé! khó quá nhỉ.
