Answer: [tex]x=5\textdegree[/tex]
Explanation:
Since we have given that
line m and line n are parallel to each other,
So,
Corresponding angles are equal , as shown in the figure ,
According to question,
[tex]19x\textdegree=180\textdegree-17x\textdegree\\\\19x\textdegree+17x\textdegree=180\\\\36x\textdegree=180\textdegree\\\\x=\frac{180}{36}\\\\x=5\textdegree[/tex]
Hence, [tex]x=5\textdegree[/tex]
