Answer 1

Answer:

a)x=130 y=130 z=130          b)x=28 y=112 z=28

Step-by-step explanation:

a)x+50=180

x=180-50=130

x=y (vertically opposite angles are equal)

x=y=130

y=z=130( alternate angles are equal)

x=130 y=130 z=130(not sure that first one is correct)

b)y=112 opposite angles are equal

upper triangle:

40+x+y=180( sum of angles in triangle is 180)

40+x+112=180

x=180-152

x=28

z=x=28(alternate angles)

therefore x=28 y=112 z=28
