Heya mate!!

We have to find the measure of angles x y and Z

As we know the adjacent angles sum 180° in a Parallelogram.

Angle ABC + EBC =. 180°

$so \: angle \: abc \: will \: be \: 100$

$angle \: b \: = 100$

$angle \: b \: + \: angle \: c \: = 180 \\ 100 + y = 180 \\ y = 80$

$x + y = 180 \\ x + 100 = 180 \\ x = 80$

$x + z = 180 \\ 80 + z = 180 \\ z =100$

Hope it helps u dear✌️✌️
