Question

plz solve this....................

Answer 1

Answer:

Here, x = 100°, y = 80° and z = 80°

Step-by-step explanation:

We know

Sum of adjacent angles in a parallelogram is 180°

⇒ 80° + x = 180°

⇒ x = 100°

Opposite angles of a parallelogram are equal,

⇒ y =  80°

Also, opposite sides of a parallelogram are equal.

Thus, y and z are Alternate Interior Angles.

Alternate Interior angles are always equal.

⇒ z = y

⇒ z = 80°
