nomor 6&7 kak bantu dong
Jawaban:
6. e = 12√3 cm
d = 12 cm
7. 64√3 cm²
Penjelasan dengan langkah-langkah:
6. Sin 60° = 1/2 √3
depan/miring = 1/2 √3
depan/24 = 1/2 √3
depan = 12√3
e = 12√3 cm
Cos 60° = 1/2
samping/miring = 1/2
samping/24 = 1/2
samping = 12
d = 12 cm
7. Sin 30° = 1/2
depan/miring = 1/2
depan/8 = 1/2
depan = 4
NK = 4 cm
Cos 30° = 1/2 √3
samping/miring = 1/2 √3
samping/8 = 1/2 √3
samping = 4√3
KL = 4√3 cm
Luas KLMN = 4 × 4√3
= 64√3 cm²
