Please help and explain reasoning

For this problem, let the universal set \( U = \{1, 2, 3, ..., 30\} \), and \( A \) be the elements \( a \) of \( U \) such that \( a + 2 \) is congruent to 0, mod 3. Suppose that \( B \) is a subset of \( U \) such that \( |A| = |B| \) and \( |\overline{A \cup B}| = 13 \). Then find \( |A \cap B| \). Explain your reasoning in detail.
