Question

pada gambar berikut segitiga abc siku siku di a dan de sejajar di ab. hitunglah panjang x, y dan z​

Answer 1

Materi : Kesebangunan dan Kekonggruenan

Panjang x

x² = 15² - 12²

x² = 225 - 144

x² = 81

x = 9 cm

Panjang z

a¹ = 12 , b¹ = x = 9

a² = z , b² = x + 3 = 12

________________/

a²/a¹ = b²/b¹

z/12 = 12/9

z = 12 × 4/3

z = 4 × 4

z = 16 cm

Panjang y

a¹ = 12 , b¹ = 15

a² = z = 16 , b² = y + 15

______________/

a²/a¹ = b²/b¹

16/12 = ( y + 15 )/15

y + 15 = 15 × 4/3

y = 5 × 4 - 15

y = 5 cm

Semoga bisa membantu

Answer 2

Jawaban:

x = 9 cm

y = 5 cm

z = 16 cm

Penjelasan dengan langkah-langkah:

Panjang x

x² = 15² - 12²

x² = 225 - 144

x = √81

x = 9 cm

..

Panjang z

z / 12 cm = 9+3 cm / 9 cm

z / 12 cm = 12 cm / 9 cm

z = 12 cm x 12 cm / 9 cm

z = 144 cm / 9 cm

z = 16 cm

..

panjang y

(y + 15)² = 16² + 12²

(y + 15)² = 256 + 144

(y + 15)² = 400

y + 15 = √400

y + 15 = 20

y = 20 - 15

y = 5 cm
