tolong jawab in no nya 1-3 plissssssssssssssssssssss
Jawab:
1. Untung Rp, 260.000
2. 576 cm2
3. 122°
Penjelasan dengan langkah-langkah:
1. = (40 x 14.000 + 60 x 10.000) - 900.000
= (560.000 + 600.000) - 900.000
= 1.160.000 - 900.000
= 260.000
2. sisi = 96 : 4
= 24
persegi = 24 x 24
= 576 cm2
3. 5x - 23 + 2x = 180 <PQS = 5x - 23
7x - 23 = 180 = 5(29) - 23
7x = 180 + 23 = 145 - 23
7x = 203 = 122°
x = 203 : 7
x = 29
maaf kalau salah
