Segitiga Kecil= STQ
DIKET
Segitiga besar=
PR= 12
PQ= 3x.. x= TQ yg belum diketahui
Segitiga kecil=
ST= 8
TQ= x
Penyelesaian:
PR/ST = PQ
12/8 = 3x
X = 8/12 × 3
X = 2
untuk mencari TQ
TQ = PQ
TQ = PT + x
TQ = 3 + 2
TQ = 5
--- = ------- (kali silang)
8 tq
8(3+tq)=12tq
24+8tq=12tq (kumpulkan)
8tq-12tq=-24
-4tq=-24
tq=-24/-4=6
Padahal ada jawabannya tuh digambar
