a//b (vì cùng vuông góc với d)

\(\Rightarrow\widehat{A1}=\widehat{B1}\) ( Hai góc so le ngoài )

Mà

\(\widehat{B1}+75^0=180\) ( hai góc kề bù )

\(\Rightarrow\widehat{B1}=\widehat{A1}=105^0\)

\(\Rightarrow\widehat{B1}+\widehat{A1}=105^0.2=210^0\)

\(2x=3y=5z\)

\(\Rightarrow\frac{2x}{30}=\frac{3y}{30}=\frac{5z}{30}\)

\(\Rightarrow\frac{x}{15}=\frac{y}{10}=\frac{z}{6}\)

Áp dụng tc của dãy tỉ số bằng nhau Ta có

\(\frac{x}{15}=\frac{y}{10}=\frac{z}{6}=\frac{x+y+z}{15+10-6}=\frac{95}{19}=5\)

=>\(\begin{cases}x=75\\y=50\\z=30\end{cases}\)

Vậy x=75;y=50;z=30

\(\frac{x}{2}=\frac{y}{3}=\frac{z}{3}\)

\(\Rightarrow\frac{x}{3}=\frac{2y}{6}=\frac{2z}{9}\)

Áp ụng tc của dãy tỉ số bằng nhau Ta có

\(\frac{x}{3}=\frac{2y}{6}=\frac{3z}{9}=\frac{x+2y-3z}{3+6-9}=-\frac{20}{0}\)
