Question

plz help me plz help guys​

Answer 1

Answer:

In first parallelogram, y = 112° as opposite angles are equal.

x becomes 180 - 112 - 40 = 28°.

z = x as Alternate Angles are equal so z = 28°

In second parallelogram, z = CBA = 80° as corresponding angles are equal.

z and DCB are linear pair so DCB is 180 - 80 = 100°.

Opposit angles are equal so y is 80° and x is 100°.

Answer 2

Answer:

since figure ABCD is a parallelogram opposite angles are equal in measore so

angle y=112° and angle x =40°

angle z=40×2=80°

In figure ii)

angle y=80°

angle x= (360-(80+80)÷2

=200÷2=100°

angle z=80°
