Question

if AB || CD, find x,y,z​

Answer 1

Answer:

180-120=60

y=60,

(y+x)+40=180

60+40+x=180

180-100=80

x=80,

x+y+z=180

80+60+z=180

180-140=40

z=40

Answer 2

Answer:

x= 80° & z= 40°( Alternate interior angles of two parallal lines is equal)

y=180°-(80°+40°) =160°[ angles on a straight line\ Linear pairs\ Angle sum property]
