Question

pls give me these answer



​

Answer 1

Answer:

1)x=20, z=40, y=100

2)x=42, y=12, z=102

Step-by-step explanation:

1)there will be linear pair use in all so there fore we have to subtract x,y,z

therefore,

180-60=x

180-40=z

180-80=y

2)it is parallelogram therefore its opposite sides are equall therefore,

144-42=102

angle a =angle x

x=42

and angle y will get by angle sum property

therefore,

x+z+3y=180

42+102+3y=180

144+3y=180

3y=180-144

3y=36

y=36/3

y=12
