Jika diketahui panjang AC=15 cm dan panjang AB=20 cm,maka panjang BD adalah... plissss bantu :(

[tex]bd = \sqrt{ab {}^{2} + ac {}^{2} } \\ bd = \sqrt{20 {}^{2} + 15 {}^{2} } \\ bd = \sqrt{400 + 225} \\ bd = \sqrt{625 } \\ bd = 25cm[/tex]

[tex]bd = \sqrt{15 {}^ + {20 {}^{2} } } \\ bd = \sqrt{225 + 400 } \\ bd = \sqrt{625} \\ bd = 25[/tex]
BD =25
