The answer is D, All of them!
Answer:
a = 23 degrees (brainliest?)
Explanation:
<em>supplementary line </em>is <u>180 degrees</u>
180 - 157 = 23
This is impossible to answer without knowing what the sets A and B contain (and what ξ even refers to - universal set?).
However, we have
(A U B)' = A' ∩ B'
so that
(A ∩ B) U (A U B)' = (A ∩ B) U (A' ∩ B') = (A U A') ∩ (B U B')
If ξ is indeed the universal set, then both A U A' = ξ and B U B' = ξ, so we end up with ξ ∩ ξ = ξ.
