bantuin dong ya​

Answer 1

Verified answer

Penjelasan dengan langkah-langkah:

ac = 17 cm

bc = 10 cm

dc = 8 cm

a. panjang ad

ad = √(ac² - dc²)

ad = √(17² - 8²)

ad = √(289 - 64)

ad = √225

ad = 15 cm

b. panjang db

db = √(bc² - dc²)

db = √(10² - 8²)

db = √(100 - 64)

db = √36

db = 6 cm

c. panjang ab

= ad + db

= 15 + 6

= 21 cm

Answer 2

Jawaban:

- AD = 15 cm

- BD = 6 cm

- AB = 21 cm

Penjelasan dengan langkah-langkah:

- AD² = AC²-CD²

AD² = 17²-8²

AD² = 289-64

AD² = 225

AD = √225

AD = 15 cm

- BD² = BC²-CD²

BD² = 10²-8²

BD² = 100-64

BD² = 36

BD = √36

BD = 6 cm

- AB = AD+BD

AB = 15+6

AB = 21 cm
