Answer:
x=y=90
Step-by-step explanation:
we know that <abc=180
=> <abe+<cbe=180
=> 2<pbe+2<ebq=180 [pb bisects <abe and bq bisects ebc]
=> <pbe+<ebq=90
=> <pbq=90
Similarly, <peq=90
in pbqe,
<p+<b+<q+<e=360
=> 90+90+<p+<q=360
=> <p+<q=180 [eq 1]
also, <abe=<bef [alternate interior angle]
=> 2<pbe=2<beq
=> <pbe=<beq
=> pb||eq
similarly, bq||pe
=>pbqe is a ||gram
=> <p=<q
=> <bpe=<bqe [vertical opposite]
=> y=x=90 [from eq 1]
