In a \( \triangle A B C, A D \) is the bisector of \( \angle A \).
(i) If \( A B=6.4 \mathrm{~cm}, A C=8 \mathrm{~cm} \) and \( B D=5.6 \mathrm{~cm} \), find \( D C \).
(ii) If \( A B=10 \mathrm{~cm}, A C=14 \mathrm{~cm} \) and \( B C=6 \mathrm{~cm} \), find \( B D \) and \( D C \).
(iii) If \( A B=5.6 \mathrm{~cm}, B D=3.2 \mathrm{~cm} \) and \( B C=6 \mathrm{~cm} \), find \( A C \).
(iv) If \( A B=5.6 \mathrm{~cm}, A C=4 \mathrm{~cm} \) and \( D C=3 \mathrm{~cm} \), find \( B C \).
