$\longmapsto\tt{40∘ + u=180°}$

$\longmapsto\tt{u=140°}$

$\longmapsto\tt{ω+u=180°}$

$\longmapsto\tt{ω=180°−u}$

$\longmapsto\tt{40°}$

$\longmapsto\tt{∠z=70°(vertically \: opposite \: angles)}$

$\longmapsto\tt{∠y+∠z=180°}$

$\longmapsto\tt{∠y=180°−∠z}$

$\longmapsto\tt{180°−70°}$

$\longmapsto\tt{110°}$

$\longmapsto\tt{ω+x=180°}$

$\longmapsto\tt{∴x=140°}$
