Answer 1

Pls mark it brainliest

And follow me

Answer:

To find X

40 + 20 + x = 180 [angle sum property]

60 + x = 180

X = 180 - 60

X = 120°

To find Y

X + y = 180 [linear pair]

120 + y = 180

Y = 180 - 120

Y = 60°

To find Z

50 + y + z = 180 [angle sum property]

50 + 60 + z = 180

110 + z = 180

Z = 180 - 110

Z = 70°

Hence values are:

X = 120°

Y = 60°

Z = 70°
