Question

in figure 10.1 29 L1 parallel to L2 what is X + Y in terms of w and Z

Answer 1

clearly X = W. ( bcoz angles on same side of
transverse)
and z = 180 - y

or y = 180 - z

X+ y = W+ 180 - z

hope it helps

Answer 2

Answer:

below

Step-by-step explanation:

x=w(co interior angle)

y=180- z

x-y =w+180 -z
