a: \(\Leftrightarrow\left(3x-1\right)^4\cdot\left(3x-2\right)\cdot3x=0\)

\(\Leftrightarrow\left[{}\begin{matrix}x=\dfrac{1}{3}\\x=\dfrac{2}{3}\\x=0\end{matrix}\right.\)

Kẻ CD//AB thì CD//MN

Do đó \(\widehat{ACD}=\widehat{CAB}=41^0;\widehat{MCD}=\widehat{CMN}=54^0\) (so le trong)

Vậy \(\widehat{ACM}=\widehat{ACD}+\widehat{DCM}=41^0+54^0=95^0\)

Ta có: \(3x=4y\Rightarrow\dfrac{x}{4}=\dfrac{y}{3}\Rightarrow\dfrac{x}{20}=\dfrac{y}{15}\)

            \(2y=5z\Rightarrow\dfrac{y}{5}=\dfrac{z}{2}\Rightarrow\dfrac{y}{15}=\dfrac{z}{6}\)

Áp dụng t/c dtsbn:

\(\dfrac{x}{20}=\dfrac{y}{15}=\dfrac{z}{6}=\dfrac{x+z}{20+6}=\dfrac{52}{26}=2\)

\(\Rightarrow\left\{{}\begin{matrix}x=20.2=40\\y=15.2=30\\z=6.2=12\end{matrix}\right.\)
