TOLONG BANTU JAWAB MATEMATIKA
Diketahui:
- DP : PA = 1 : 2
- AB = 18 cm
- DC = 6 cm
Ditanyakan:
- PQ = ... cm?
Penyelesaian:
[tex]PQ = \frac{(AB \times DP) + (CD \times PA)}{DP + PA} \\ \\ PQ = \frac{(18 \times 1) + (6 \times 2)}{1 + 2} \\ \\ PQ = \frac{18 + 12}{3} \\ \\ PQ= \frac{30}{3} \\ \\ PQ = 10 \: cm \to \color{blue}{opsi \: b}[/tex]
