\huge{\underbrace{\sf{\red{Answer:}}}}

\large{\boxed{\sf{\purple{ \angle 1 = 75°, \angle 2 = 105°,\angle 3 = 75°}}}}

\large{\boxed{\sf{\purple{ \angle 4 = 105°, \angle 5 = 75°,\angle 6 = 105°}}}}

\large{\boxed{\sf{\purple{ \angle 7 = 75°, \angle 8 = 105°}}}}

\huge{\underbrace{\sf{\pink{Explanation:}}}}

\displaystyle{\sf{ \angle 1 + \angle 2 = 180°\:\:\:\:\:| \because\:Linear\:pair\:axiom}}

\implies{\sf{ 75° + \angle 2 = 180°}}

\implies{\sf{ \angle 2 = 180° - 75°}}

\implies{\sf{\angle 2 = 105°}}

\displaystyle{\sf{ \angle 2 = \angle 4 = 105°\:\:\:| \because Vertically\:Opposite\:Angle}}

\displaystyle{\sf{ \angle 1 = \angle 3 = 75°\:\:\:| \because Vertically\:Opposite\:Angle}}

\displaystyle{\sf{ \angle 2 = \angle 6 = 105°\:\:\:| \because Corresponding\:Angles}}

\displaystyle{\sf{ \angle 3 = \angle 7 = 75°\:\:\:| \because Corresponding\:Angles}}

\displaystyle{\sf{ \angle 4= \angle 8= 105°\:\:\:| \because Corresponding\:Angles}}

\displaystyle{\sf{ \angle 1 = \angle 5 = 75°\:\:\:| \because Corresponding\:Angles}}
