Jawaban:
Teorema Pythagoras
1. Alas (a) = 10 cm
Tinggi (t) = 24 cm
sisi miring ( x ) = ?
penyelesaian:
[tex] {x}^{2} = {a}^{2} + {t}^{2} [/tex]
[tex]x = \sqrt{ {a}^{2} + {t}^{2} } [/tex]
[tex]x = \sqrt{ {10}^{2} + {24}^{2} } [/tex]
[tex]x = \sqrt{100 + 576} [/tex]
[tex]x = \sqrt{676} [/tex]
[tex]x = 26 \: cm[/tex]
2. sisi miring ( x) = 12 cm
alas (a) = 8 cm
tinggi (t) = ..?
Penyelesaian:
[tex] {t}^{2} = {x}^{2} - {a}^{2} [/tex]
[tex]t = \sqrt{ {x}^{2} - {a}^{2} } [/tex]
[tex]t = \sqrt{ {12}^{2} - {8}^{2} } [/tex]
[tex]t = \sqrt{144 - 64} [/tex]
[tex]t = \sqrt{80} [/tex]
[tex]t = \sqrt{16 \times 5} [/tex]
[tex]t = \sqrt{16} \times \sqrt{5} [/tex]
[tex]t = 4 \sqrt{5} [/tex]
3. Alas (a) = 5 cm
sisi miring (x) = 13 cm
tinggi (t)= ..?
Penyelesaian:
[tex] {t}^{2 } = {x}^{2} - {a}^{2} [/tex]
[tex]t = \sqrt{ {x}^{2} - {a}^{2} } [/tex]
[tex]t = \sqrt{ {13}^{2} - {5}^{2} } [/tex]
[tex]t = \sqrt{169 - 25} [/tex]
[tex]t = \sqrt{144} [/tex]
[tex]t = 12 \: cm[/tex]
