Question

Panjang PS + TQ =
dengan caranya ya..

Answer 1

Verified answer

X / y = x per y

PR = PS + SR
PR = PS + 3

ST / RQ = PS / PR
10 / 15 = PS / (PS + 3)
15 × PS = 10 × (PS + 3)
15PS = 10PS + 30
15PS - 10PS = 30
5PS = 30
PS = 6 cm

PQ = PT + TQ
PQ = 6 + TQ

ST / RQ = PT / PQ
10 / 15 = 6 / (6 + TQ)
6 × 15 = 10 × (6 + TQ)
90 = 60 + 10TQ
90 - 60 = 10TQ
30 = 10TQ
TQ = 3 cm

PS + TQ = 6 cm + 3 cm
= 9 cm (tidak ada pilihan jawaban)
