Question

Pada gambar segitiga berikut hitunglah nilai x.

a.10 16

b.48 20​

Answer 1

Jawaban:

Bagian a.

[tex] \sf {x}^{2} = {10}^{2} + {48}^{2} [/tex]

[tex] \sf {x}^{2} = 100 + 2.304[/tex]

[tex] \sf {x}^{2} = 2.404[/tex]

[tex] \sf x = \sqrt{2.404} [/tex]

[tex] \sf x = \sqrt{4 \times 601} [/tex]

[tex] \sf x = \sqrt{4} \times \sqrt{601} [/tex]

[tex] \sf x = 2 \sqrt{601} [/tex]

Bagian b.

[tex] \sf {x}^{2} = {16}^{2} + {20}^{2} [/tex]

[tex] \sf {x}^{2} = 256 + 400[/tex]

[tex] \sf {x}^{2} = 656[/tex]

[tex] \sf x = \sqrt{656} [/tex]

[tex] \sf x = \sqrt{16 \times 41} [/tex]

[tex] \sf x = \sqrt{16} \times \sqrt{41} [/tex]

[tex] \sf x = 4 \sqrt{41} [/tex]
