A) \[x=30{}^\circ ,\text{ }y=50{}^\circ \]
B) \[x=25{}^\circ ,\text{ }y=75{}^\circ \]
C) \[x=50{}^\circ ,y=30{}^\circ \]
D) \[x=50{}^\circ ,y=25{}^\circ \]
Correct Answer: C
Solution :
(c): Since \[BE||DC\Rightarrow \angle ABE=100{}^\circ \] and \[\angle x=50{}^\circ \] In \[\Delta ABE,\] \[\angle y=180{}^\circ -100{}^\circ -50{}^\circ =30{}^\circ \]
