Answer 1

Answer:

y = 42 degree because of vertically opposite angles

X = 42 degree

z = 75 degree

please follow me for this answer pleaseeee

Answer 2

Answer:

42°+63°+c=180° [angle sum property]

c=180° -105° = 75°

42° = y (vertically opposite angles)

y = x = 42° [alternate angles]

z+63°+ 42°= 180° [linear pair]

z +63+42° =180° (because x= z)

z = 180° - 105°

z = 75°
