Tolong yaa lgi remed nih :D​

Jawaban:

Hmmm

Penjelasan dengan langkah-langkah:

Rs=16

St=12

16^2+12^2=x^2

256+144=x^2

X. =400

X. =20

16+20+12=48

B..48

Penjelasan dengan langkah-langkah:

Panjang RT

RT = √RS² + ST²

= √16² + 12²

= √256 + 144

= √400

= 20 cm

Keliling segitiga

k∆ = a + b + c

k∆ = 16 + 12 + 20

k∆ = 48 Cm (B)
