in the figure ab parallel to dc,de parallel to ac,then

Answer 1

z+x=180 they are complementary,consecutive exterior angles, then y=z same consecutive interior angles

Answer 2

these are the options1. w = 180 – x
2. x + y = a – z
3. y = b
4. x – w = z – y
5. None of these

Answer 3

i think 1 is the answer

Answer 4

then y is also equal to b alternate angles

Answer 5

x+w=180 and y+z=180

Answer 6

whats the question ?
and the figure doesn't look correct.. you have variables a, b in many places..

Answer 7

in my opinion i think all are correct

Answer 8

variable confusing me lol
