Jawab:
Garis
Perbandingan segmen garis
Penjelasan dengan langkah-langkah:
S (3, 7, -6)
T (- 7, 2, 9 )
O pada garis ST , sehingga SO = 1/5 ST
5 SO = ST
5( o - s ) = (t - s)
5 o - 5 s = t - s
5 o = t - s + 5 s
5 o = t + 4s
O = 1/5 { T + 4 (S) }
T= (-7, 2, 9)
4S = 4 { 3, 7 ,-6} = {12, 28, -24 }
T + 4 S = (-7 + 12) ,(2 + 28) , (9- 24)
T + 4S = (5 , 30, -15)
O = 1/5 { T + 4 S)
O = 1/5 { 5, 30 , -15 }
O = { 1, 6, - 3 }
