Answer 1

Jawaban:

1. AB = 4√5 cm

AC = 8√5 cm

2. x = 18 ¾ cm

Penjelasan dengan langkah-langkah:

1.

[tex] \frac{16}{ad} = \frac{ad}{4} \\ ad = \sqrt{16 \times 4} \\ = \sqrt{64} = 8[/tex]

[tex]ab = \sqrt{8 {}^{2} + {4}^{2} } \\ = \sqrt{64 + 16} \\ = \sqrt{80} = 4 \sqrt{5} \\ ac = \sqrt{ {16}^{2} + {8}^{2} } \\ = \sqrt{256 + 64} \\ = \sqrt{320} = 8 \sqrt{5} [/tex]

2.

[tex]\frac{20}{x} = \frac{16}{15} \\ x = \frac{20 \times 15}{16} \\ = \frac{75}{4} = 18 \frac{3}{4} [/tex]
