Answer 1

Hey there!!

Angle 2 is given by 12 x and hence angle 4 would become 12x due to vertically opposite angle.

Angle 1 is given by 3x and hence, angle 4 + angle 1 = 180 ( straight angles )

... 12x + 3x = 180

... 15x = 180

... x = 12

Angle 4 = 12x

... 12 ( 12 )

... 144°

Hope my answer helps!!

Answer 2

angle 4 = 12x =12 times(12)=144
