Jawaban nya apa?tolong ....saya bingung ,,saya pusing

10^2+8^2
100+64
164+5
169
=13

MAPEL = MATEMATIKA
KELAS = 8
BAB = PHYTAGORAS

diketahui =
BC = 13cm
CD = 5cm
AE = 8cm
AB = 10cm

ditanya = ED??

- panjang BD :
BD = √BC² - CD²
BD = √13² - 5²
BD = √169 - 25
BD = √144
BD = 12cm

- panjang BE :
BE = √AB² - AE²
BE = √10² - 8²
BE = √100 - 64
BE = √36
BE = 6cm

panjang ED :
= BD - BE
= 12cm - 6cm
= 6cm

semoga membantu
