Will recommend to keep in touch with picture as name of angles are based on it!

$\\$

So as you can see BA is parallel to DC as the arrow signs are made on it. And the figure has four sides , therefore we get to know that the above picture is of parallelogram.

$\\$

$\rm\angle B = \angle D$

How ?

As we know it's a parallelogram, so there's one property of parallelogram that opposite sides of Angle are equal.

$\\$

$\hookrightarrow \sf2x =130 \degree$

$\\$

$\hookrightarrow \sf x =130 \degree\div 2 \degree$

$\\$

$\hookrightarrow \sf x = \dfrac{130}{2}$

$\\$

$\hookrightarrow \sf x = \dfrac{13 \times 10}{2}$

$\\$

$\hookrightarrow \sf x = \dfrac{13 \times\cancel{ 10}}{\cancel2}$

$\\$

$\hookrightarrow \sf x = \dfrac{13 \times5}{1}$

$\\$

$\hookrightarrow \sf x =13 \times5$

$\\$

$\hookrightarrow \sf x =65 \degree$

$\\$

Now Let's find value of y.

$\rm \angle DAB =\angle DCB$

How ?

As we know it's a parallelogram, so there's one property of parallelogram that opposite sides of Angle are equal.

$\\$

$\dashrightarrow \rm x = y$

$\\$

$\dashrightarrow \rm 65 = y$

$\\$

$\dashrightarrow \bf y = 65 \degree$

$\\$

y + z + 60° = 180°

angles on same line

$\\$

65 + 60 + z = 180°
125° + z = 180°
z = 180° - 125 °
z = 55°

At last :-

x = 65°

y = 65°

z = 55°
