Gọi số lúa 3 đội gặt được là a;b;c ( ha )

=> c - a=1

Vì năng suất của mỗi máy đều như nhau

\(\Rightarrow\frac{a}{10}=\frac{b}{13}=\frac{c}{15}\)

Áp dụng tc của dãy tỉ số bằng nhau ta có

\(\frac{a}{10}=\frac{b}{13}=\frac{c}{15}=\frac{c-a}{15-10}=\frac{1}{5}\)

=>a=2

   b=\(\frac{13}{5}\)

c=3

Vậy số lúa của 3 đội lần luowtl là 2 ; \(\frac{13}{5}\) ; 3

Gọi Am là tia phân giác của góc A ; Cn là tia phân giác của góc C

Ta có

\(\widehat{BAC}=\widehat{ACx}\) (Cx//AB ; hai góc so le trong )

Mặt khác

\(\widehat{A1}=\frac{1}{1}\widehat{BAC}\)( Am là tia phân giác )

\(\widehat{C1}=\frac{1}{2}\widehat{ACx}\) ( Cn là tia phân giác )

\(\Rightarrow\widehat{A1}=\widehat{C1}\)

Mà \(\widehat{A1};\widehat{C1}\) so le trong

=> Am//Cn (đpcm)
