\qquad\qquad\huge\underline{{\sf Answer}}

Let's solve ~

Here we can observe that Line BD is parallel to line AC.

so,

\qquad \tt \dashrightarrow \: \angle z = 30 \degree

[ by Alternate interior angles ]

\qquad \tt \dashrightarrow \: \angle x =  \angle A = 50 \degree

[ opposite angles of a Parallelogram ]

\qquad \tt \dashrightarrow \: \angle x +  \angle y + 30 \degree = 180 \degree

[ by Angle sum property of Triangle ]

\qquad \tt \dashrightarrow \: 50 +  \angle y + 30 \degree = 180 \degree

\qquad \tt \dashrightarrow \:    \angle y + 80 \degree = 180 \degree

\qquad \tt \dashrightarrow \:    \angle y   = 180  - 80

\qquad \tt \dashrightarrow \: \angle y = 100 \degree
