Penjelasan dengan langkah-langkah:
NOMOR 1
QR² = PQ² - PR²
QR = √26×26 - 10×10
QR = √576
QR = 24 cm
Nomor 2 saya tidak faham
NOMOR 3
PQ² = RQ² - PR²
PQ = √48×48 - 14×14
PQ = √2.500
PQ = 50 cm
NOMOR 4
cari CD dulu
CD² = 15² - 9²
CD =√15×15 - 9×9
CD = √144
CD = 12 cm
Cari ED dulu
ED² = 10² - 6²
ED = √100 - 36
ED = 8 cm
sekarang cari CE
CE = CD - ED
CE = 12 - 8
CE = 4 cm
