Jawaban:
12cm
Penjelasan dengan langkah-langkah:
DB = 9 cm
ADC sebangun BDC
AD/CD = CD/BD
CD² = AD.BD = 16.9
CD = √144 = 12cm
D. 12 cm
AD = AB - BD
*= 25 - 16 = 9 cm
[tex] \frac{bd}{cd} = \frac{bc}{ac} = \frac{cd}{ac} [/tex]
[tex] \frac{bd}{cd} = \frac{cd}{ad} \\ (cd {)}^{2} = bd \times ad \\ cd = \sqrt{bd \times ad} \\ = \sqrt{ {16}^{} \times {9}^{} } \\ = \sqrt{144} \\ = 12[/tex]
