please solve this query(there is only one)

Answer 1

Answer:

75

Step-by-step explanation:

angle CEF + angle ECD = 180

138 + angle ECD = 180

angle ECD = 180-138 = 42

angle BCD = 42 + 33 = 75

angle BCD = angle ABC

angle ABC = 75

Answer 2

Answer:

I think the answer is

75°

because

as we can see that ef||cd so,if we extend CD on left side and name as O

so by alternate interior angle ECO=138°

so angle ECD=180-138

=42°

so,angle BCD=33+42

=75°

so by alternate interior

angle ABC=75°

hope it helps you..
