Question

Minta tolong jawab, hehe... kalau bisa dua duanya ya.

Answer 1

Verified answer

1. 180° 3x + 15 + 2x 10
180° = 5x +25
155 = 5x
x = 31
masukkan : KLN = 3x+15
3(31)+15
108(jawaban nya gak ada)

2. x = 25°
masukkan : 50+3(25)
50+75
=125
180°-125°
=55°

skian;*

Answer 2

Jawabannya:
23. 180° = 3x+15+2x-10
180° = 5x-5x
175= 5x
x= 35
2x+10= 2(35)+10+5
= 70+10+5
= 80+5
=85° → C

24. x= 25°
50+3(25)
50+75
= 125°

Karena segitiga sama sisi maka sudutnya 180° → 180°-125°=55° → C
