Answer 1

Jawaban:

4. x = 4,25 cm dan y = 9 cm

5. 25 cm dan 28 cm

6. 5 cm

7. 14,4 cm

Penjelasan dengan langkah-langkah:

4.

x/8,5 = 8/16

x = 8,5 × 8/16

x = 4,25 cm

..

y/18 = 8/16

y = 9 cm

..

5. x/18 = 16/12

x = 24 cm

..

y/21 = 16/12

y = 28 cm

..

6. x/10 = 21/14

x = 15

TR = 15 - 10

TR = 5 cm

..

7. x + 7,2/x = 15/10

x + 7,2 = 15x/10

10x + 72 = 15x

72 = 5x

x = 14,4
