Question

Soal mat yg sama cuman lebih bingung busat aku
Yang nomor 1 dan 2

Answer 1

1. < PQS + < SQR = 180°
3c + 45 + 30° = 180°
3c + 75 = 180°
3c = 180 - 105
3c = 105
c = 105/3 = 35°
< PQS = 3(35) + 45° = 150°
2. < KLN + < NLM = 180°
4d + 60° + d = 180°
4d + d = 180° - 60°
5d = 120°
d = 120°/5 = 24°
< KLN = 4(24) +60° = 156°
