Answer 2

i) z = 45+z = 180

z=180-45

z=135 deg

ii) y = 40+y=180

y= 180-40 = 140 deg

x = 140+x = 180

x = 180-140 = 40 deg

z = 40+ z = 180

z = 180-40 = 140deg

iii) x = 55+x = 90

x = 90-55 = 35 deg

iv) z = 47+z = 90

z = 90-47 = 43 deg

y = 43+y = 180

y= 180-43 = 137 deg

x = 137+x = 180

x=180-137 = 43 deg

v) x+40+x-10 = 180

2x+30 = 180

2x = 180-30 = 150

x = 150/2 = 75

x+40 = 75+40 = 115 deg

x-10 = 75-10 = 65 deg

y = 115 + y = 180

y = 180-115 = 65 deg

z = 65+z = 180

z = 180-65 = 115 deg

vi) z = 60+z = 180

z = 180-60 = 120 deg

x = 120 + x + x = 180

120 + 2x = 180

2x = 180-120= 60

x = 60/2 = 30 deg

x = 30 deg

y = y + y + 60 = 180

2y+60 = 180

2y = 180-60 = 120

y = 120/2 = 60 deg

y = 60 deg

These are the answers.

Hope you have a great day! :)
