ada yg tau caranya ngga? klo ada bantu jawab ya soalnya butuh banget☺️
Penjelasan dengan langkah-langkah:
1. Persentase kerugian = (160-140)/160 x 100%
= 20/160 x 100%
= 200/16 %
= 12,5%
2. 2x = 150 → x = 150/2 = 75°
3y = 52 → y = 52/3 = 17,333°
5p + 3 = 68 → 5p = 68-3 → p = 65/5 = 13°
3. 4/7 = y/14
y = 14/7 × 4 = 2 × 4 = 8
8/(8+x) = 4/7
4(8+x) = 8(7)
32 + 4x = 56
4x = 56 – 32
4x = 24
x = 24/4 = 6
4. 2x + 10 + 40 = 180
2x = 180 – 50
x = 130/2 = 65°
k = 2(65) + 10
k = 130 + 10 = 140°
5. 3x - 45 = x - 23
3x - x = 45 - 23
2x = 22
x = 22/2 = 11
sudut BCF = x - 21
