Answer 1

Jawaban:

[tex]a.4\sqrt{3}\:dan\:4[/tex]

Penjelasan dengan langkah-langkah:

[tex]\frac{Sin\:90°}{8}=\frac{Sin\:60°}{KL}[/tex]

[tex]\frac{Sin \:90°}{8}=\frac{Sin\:60°}{P}[/tex]

[tex]\frac{1}{8}=\frac{\frac{1}{2}\sqrt{3}}{P}[/tex]

[tex]P=\frac{1}{2}\sqrt{3} \times 8[/tex]

[tex]P=4\sqrt{3}\\\\[/tex]

[tex]\frac{Sin\:90°}{8}=\frac{Sin\:30°}{KN}[/tex]

[tex]\frac{Sin \:90°}{8}=\frac{Sin\:60°}{L}[/tex]

[tex]\frac{1}{8}=\frac{\frac{1}{2}}{L}[/tex]

[tex]P=\frac{1}{2}\times 8[/tex]

[tex]P=4\\\\[/tex]

Answer 2

Verified answer

Jawab:

Penjelasan dengan langkah-langkah:

sin KLN = KN/LN

sin 30 = KN/8

½ = KN/8

2KN = 8

KN = 8/2 = 4

KL² = LN² - KN²

KL² = 8² - 4²

KL² = 64 - 16

KL² = 48

KL = V48

KL = 4V3

V = akar kuadrat

Jadi, panjang = 4V3 dan lebar = 4 (A).
