a: Trên cùng một nửa mặt phẳng bờ chứa tia Ox, ta có: \(\widehat{xOy}< \widehat{xOz}\left(30^0< 100^0\right)\)
nên tia Oy nằm giữa hai tia Ox và Oz
=>\(\widehat{xOy}+\widehat{yOz}=\widehat{xOz}\)
=>\(\widehat{yOz}=100^0-30^0=70^0\)
Vì tia Ot nằm trong góc yOz
nên tia Ot nằm giữa hai tia Oy,Oz
=>\(\widehat{yOt}+\widehat{zOt}=\widehat{yOz}\)
=>\(\widehat{zOt}=70^0-20^0=50^0\)
Vì \(\widehat{yOt}< \widehat{zOt}\left(20^0< 50^0\right)\)
nên Ot không là phân giác của góc yOz
b: Vì \(\widehat{zOt}< \widehat{zOx}\left(50^0< 100^0\right)\)
nên tia Ot nằm giữa hai tia Oz và Ox
=>\(\widehat{tOz}+\widehat{tOx}=\widehat{xOz}\)
=>\(\widehat{xOt}=100^0-50^0=50^0\)
Ta có: tia Ot nằm giữa hai tia Ox và Oz
mà \(\widehat{xOt}=\widehat{zOt}\left(=50^0\right)\)
nên Ot là phân giác của góc xOz
\(\dfrac{7}{12}:\dfrac{7}{9}=\dfrac{7}{12}\times\dfrac{9}{7}=\dfrac{9}{12}=\dfrac{3}{4}\)
Ta có: \(\hat{zOt}+\hat{zOy}=180^0\) (hai góc kề bù)
=>\(\hat{zOt}=180^0-\hat{zOy}\)
ta có: \(\hat{xOt}+\hat{xOy}=180^0\) (hai góc kề bù)
=>\(\hat{xOt}=180^0-\hat{xOy}\)
\(\hat{zOt}-\hat{xOt}\)
\(=\left(180^0-\hat{zOy}\right)-\left(180^0-\hat{xOy}\right)\)
\(=180^0-\hat{zOy}-180^0+\hat{xOy}=\hat{xOy}-\hat{zOy}\)
\(\left(x-2\right)^2-\left(x+1\right)\left(x-3\right)=-7\\ \Rightarrow x^2-4x+4-\left(x^2-2x-3\right)=-7\\ \Rightarrow x^2-4x+4-x^2+2x+3=-7\\ \Rightarrow-2x+7=-7\\ \Rightarrow-2x=-14\\ \Rightarrow x=-14:\left(-2\right)\\ \Rightarrow x=7\)
