Jawaban:
12. B. 20
13. B. 28
Penjelasan dengan langkah-langkah:
12. P = 180 - (180-120) - 70
= 180 - 60 - 70
= 50
Q - P = 70 - 50
= 20
13. ABC + CAB + ACB = 180 (sudut segitiga dalam)
x + 2x + 96 = 180. CAB = 2x= 2 (28) = 56
3x = 180 - 96
3x = 84
x = 84 : 3
x = 28
ABC = 180 - 56 - 96
= 28
maaf kalo salah ya
