panjang CD adalah.. mohon bantuannya ya

langkah 1 (mencari panjang BD),
[tex]ad \div bd = 2 \div 1 \\ 6 \sqrt{2} \div bd = 2 \div 1 \\ 2bd = 6 \sqrt{2} \\ bd = \frac{6 \sqrt{2} }{2} \\ bd = 3 \sqrt{2} [/tex]

langkah 2 (mencari CD),
[tex]bd \div cd = 1 \div \sqrt{2 } \\ 3 \sqrt{2} \div cd = 1 \div \sqrt{2} \\ cd = 3 \sqrt{2 } \times \sqrt{2} \\ cd = 3 \times 2 \\ cd = 6[/tex]
