QR = 40 cm
Berdasarkan aturan sudut istimewa segitiga,
(QR menghadap 90°, RS menghadap 30°)
RS/QR = 1/2
⇒ RS/40 = 1/2
⇒ RS = 20 cm
Perhatikan ΔPRS!
PR = 25 cm
Berlaku
PS² + RS² = PR²
⇒ PS² + 20² = 25²
⇒ PS² = 625 - 400
⇒ PS² = 225
⇒ PS = √225
⇒ PS = 15 cm
Jawab : C
Terimakasih semoga membantu
RS/RQ = 1/2
RS / 40 = 1/2
RS = 20
PS = √RP² - RS²
=√ 25² - 20²
= √225
= 15 cm (c)
semoga membantu
