Pls helpppppp this stuff makes no sense

Answer:
x = 5
Step-by-step explanation:
a || b and a line intersecting them is their transversal.
[tex] \therefore m\angle 1=m\angle 5\\(corresponding \:\angle 's) \\\\
\therefore 60 - 2x = 70 - 4x\\\\
\therefore 4x - 2x = 70 - 60\\\\
\therefore 2x = 10\\\\
\therefore x =\frac{10}{2} \\\\
\huge \orange {\boxed {\therefore x = 5}}[/tex]
