tolong dijawab no 27 no 26 no 29 aja

26.
KLN + NLM = 180° (1 garis lurus)
3x + 15 + 2x + 10 = 180°
5x + 25 = 180°
5x = 180°-25° = 155°
x = 155°/5 = 31°
Pelurus KLN = NLM
NLM = 2 × 31° +10° = 72°

27.
AQC + BQC = 90° (Siku siku)
6x + 4 + 5x + 9 = 90°
11x + 13 = 90°
11x = 90°-13° = 77°
x = 77° : 11 = 7°
Penyiku AQC = BQC
BQC = 5×7 + 9 = 35 + 9 = 44°

nomor 29 maaf saya tidak bisa


maaf kalau salah

itu nomer 27 maaf kalau salah
