Jawab:
PR = 15 cm
QR = 5√3 cm
Penjelasan dengan langkah-langkah:
<P = 30°
<Q = 60°
<R = 90°
PQ = 10√3 cm
Ditanya PR dan QR
PR/PQ = cos(<P)
PR/(10√3) = cos(30°)
PR/(10√3) = ½ √3
PR = ½ √3 × 10√3
PR = ½ × 10 × √3 × √3
PR = 5 × 3
PR = 15 cm
QR/PQ = cos(<Q)
QR/(10√3) = cos(60°)
QR/(10√3) = ½
QR = ½ × 10√3
QR = 5√3 cm
