Jawaban soal nomer 3 rq = 4 + 8 = 12 cm bagian soal A bangun sebagun karna ∠ RPQ = ∠RTS ∠ PQR = ∠ TSR bagian soal B mencari panjang TS rs/rq = ts/pq 6/12 = ts / 14 12 ts = 6 x 14 ts = 84/12 ts = 14 cm mencari panjang SP rs/rq = rt/rp 6/12 = 4/rp 6 rp = 4 x 12 rp = 48/6 rp = 8 cm Sp = 8 -6 = 2 cm
jawaban soal nomer 4 mencari nilai x de/ae = dc/ab 2x/6 = (x+1)/4,5 6x +6 = 9x 6x-9x = -6 -3x = -6 x = -6/-3 x = 2 mencarai BE be = 3x -1 = 3(2)-1 = 6-1 = 5 mencari CE de =2x = 2 (2) = 4 ce/be = de/ae ce/5 = 4/6 6ce = 4 x 5 ce = 20/6 ce = 3,34
rq = 4 + 8
= 12 cm
bagian soal A
bangun sebagun karna
∠ RPQ = ∠RTS
∠ PQR = ∠ TSR
bagian soal B
mencari panjang TS
rs/rq = ts/pq
6/12 = ts / 14
12 ts = 6 x 14
ts = 84/12
ts = 14 cm
mencari panjang SP
rs/rq = rt/rp
6/12 = 4/rp
6 rp = 4 x 12
rp = 48/6
rp = 8 cm
Sp = 8 -6
= 2 cm
jawaban soal nomer 4
mencari nilai x
de/ae = dc/ab
2x/6 = (x+1)/4,5
6x +6 = 9x
6x-9x = -6
-3x = -6
x = -6/-3
x = 2
mencarai BE
be = 3x -1
= 3(2)-1
= 6-1
= 5
mencari CE
de =2x
= 2 (2)
= 4
ce/be = de/ae
ce/5 = 4/6
6ce = 4 x 5
ce = 20/6
ce = 3,34
