Jawaban:
a. BE = 6cm
b. BD = 12cm
c. ED = 6Ccm
Penjelasan dengan langkah-langkah:
a.
- BE =
- BE² = AB² - AE²
- BE² = 10² - 8²
- BE² = 100 - 64
- BE² = 36
- BE = √36
- BE = 6
b.
- BD² = BC² - CD²
- BD² = 13² - 5²
- BD² = 169 - 25
- BD² = 144
- BD = √144
- BD = 12
c.
- ED = BD - BE
- ED = 12 - 6
- ED = 6
