Jawab: 14,2 m
Penjelasan dengan langkah-langkah:
didepan 90 = 2√2 = 2x1,4 = 2,8m
didepan 45 = 2m
didepan 45 = didepan 30 = 2m
ddidepan 60 = 2√3 = 2x1,7 = 3,4m
di depan 90 = 2x2= 4m
Panjang semua = (2,8+2+2) + (3,4+4) = 14,2 m
Jawaban:
Total panjang balok = 2.8 + 4 + 5.36
= 12.16 m
Penjelasan dengan langkah-langkah:
Sin 45° = 1/2 √2
depan/miring = 1/2 √2
2/miring = 1/2 √2
miring = 2 ÷ (1/2√2)
miring = 2 × 2/√2
miring = 4/√2
miring = 4/√2 × √2/√2
miring = (4√2)/2
miring = 2√2
miring = 2 × 1.4
miring = 2.8 m
Panjang balok miring kanan = 2.8 m
Sin 30° = 1/2
depan/miring = 1/2
2/miring = 1/2
miring = 2 ÷ 1/2
miring = 2 × 2
miring = 4 m
Panjang balok miring kiri = 4 m
Cos 45° = 1/2 √2
samping/miring = 1/2 √2
samping/2.8 = 1/2 √2
samping = 1.4 √2
samping = 1.4 × 1.4
samping = 1.96 m
Panjang balok kanan bawah = 1.96 m
Cos 30° = 1/2 √3
samping/miring = 1/2 √3
samping/4 = 1/2 √3
samping = 2 √3
samping = 2 × 1.7
samping = 3.4 m
Panjang balok kiri bawah = 3.4 m
Maka panjang balok bawah = 3.4 + 1.96
= 5.36 m
