Question

Please tell me the value of x, y and z in all the figures also please mention the reasons (property)

Answer 1

Answer:

27) x= 70° ( alternate)

y+z= 180°. ( linear Pair) .i)

130+ b = 180°

b = 50°

50° + 70° + y = 180° ( SOI)

y = 60°

from i) ,

60° + z = 180°

z = 130°

28) x= 60

60+90+y = 180

y= 30

30) x = 180- (30+50)

x = 100

y = 100. ( alternate)

z= 180 - 100

z= 80
