Answer 2

$by \: pythagoras \: theorem \\ \: because \: dbc \: forms \: right \: angled \: triangle \\ \\ = > {db}^{2} = {dc}^{2} + {bc}^{2} \\ = > {26}^{2} = {24}^{2} + {bc}^{2} \\ = > {26}^{2} - {24}^{2} = {bc}^{2} \\ = > 676 - 576 = {bc}^{2} \\ = > \sqrt{100} = bc \\ = > bc = 10 \\ \\ so \:bc \: measure \: 10 \: cm.$
