Bantu jawab yaa, besok harus udah siap​

Jawaban:

semoga membantu yaaa, maaf no 3 nya gabisa

Jawaban:

1) BC = √AC² – AB²

= √20² – 12²

= √400 – 144

= √256 = 16 cm

2) ED = EA – AD

= 13 – 5

= 8 cm

BD = √AB² – AD²

= √13² – 5²

= √144 = 12 cm

DC = BD/2

= 12/2 = 6 cm

EC = √ED² + DC²

= √8² + 6²

= √64 + 36

= √100 = 10 cm

3) √5² – 3³

= √25 – 9

= √16

= 4 m

Jangan lupa jadikan jawaban terbaik yaa, makasih ^-^
