Answer 1

1) x =44,y=135,z=45 2)y=59

Answer 2

Answer:

Step-by-step explanation:

In i figure x=z(VOA)

y=135

x+y=180 (Linear pair)

x=180-135=45

z=45

x=45,y=135,z=45

In ii figure:

31+y=90

y=59

y=z (VOA)

z=59

31=x(VOA)

In figure iii

x=44(VOA)

z=51(VOA)

x+y+z=180(supplementary angles )

95+y=180

y=85
