Answer 1

Verified answer

Penjelasan dengan langkah-langkah:

Gambar b

DB² = BC²+CD²

DB² = 7² + 4²

DB² = 49+16

DB² = 65

DB = √65 cm

AB² = DB²-AD²

AB² = √65² - 6²

AB² = 65-36

AB² = 29

AB = √29 cm

gambar c

Kita buat ilustrasi biar tidak ngang ngong ngang ngong

AB² = BD²+AD²

AB² = 5²+4²

AB² = 25 + 16

AB² = 44

AB = 2√11 cm

Answer 2

B) DB = √7² + 4²

= √(7(7) + (4(4)

= √49 + 16

= √65 CM

AB = √65² - 6²

= √(65 - 6)

= √29 CM

C) AB √5² + 4²

= √(5(5) + (4(4)

= √25 + 16

= √44

= √4(11)

= √2²(11)

= 2√11 CM
