Bạn đang muốn hỏi về vấn đề gì ạ?

Điều kiện \(\overline{9,2x8}\)\(>\)\(92,78\) do đó \(x\)có 1 chữ số 

\(\Rightarrow x\)\(=\)\(8;9\)

Thay vào ta đc:\(9,288;9,298\)

Vậy \(x\)\(=\)\(8;9\)

x>10,35

mà x là số tự nhiên bé nhất

nên x=11

x= 11

2. He/know/me/ a long time/ but/he/not/know/ my name.

x<17,2<y

mà x,y là các số tự nhiên chẵn

nên (x,y)\(\in\left\{0;18\right\}\)

`17,2 > x `

`=> x` là `0;2;4;...;14` hoặc `16`

`17,2 < y`

`=> y` là `18;20;22`;.... (vô hạn) 

Đề bài ngĩa là sao vậy bạn?

là seo?

ai trả lời nhanh nhất thì mình tick cho

ko

Xét ΔABC vuông tại A có \(\widehat{ABC}+\widehat{ACB}=90^0\)

=>\(2\left(\widehat{OBC}+\widehat{OCB}\right)=90^0\)

=>\(\widehat{OBC}+\widehat{OCB}=45^0\)

Xét ΔOBC có \(\widehat{OBC}+\widehat{OCB}+\widehat{BOC}=180^0\)

=>\(\widehat{BOC}+45^0=180^0\)

=>\(\widehat{BOC}=180^0-45^0=135^0\)
