Jawab:

segitiga siku
sudut 30, 60, 90
perbandingan sisi

#SMP

pada gambar
ΔQPR siku di P = 90°,  <Q  =30 dan   <R = 60
perbandingan sisi
PQ: PR :  QR =  √3 :  1 : 2
PQ = 12 cm


panjang PR
PQ : PR =  √3 : 1
PR =   (PQ) / √3
PR =  (12) /√3
PR =  12√3 /  3
PR =  4√3

panjang QR
PQ: QR = √3 : 2
QR =  2PQ / √3
QR =  2 (12) / √3
QR =  24 /√3
QR  = 24√3  /  3
QR =  8√3
