bantuu jawab kaaaa,kaloo bisa beserakan langkah" atau caranya yaaa
Penjelasan dengan langkah-langkah:
garis k //g
B1= 100°
A1= 40°
besar A2
A2 = B1 - A1
A2 = 100° - 40°
A2 = 60°
besar C2
C2 = 180 - A2
C2 = 180 - 60
C2 = 40°
besar A3
A3 = 180° - (A1 + A2)
A3 = 180° - (40 + 60)
A3 = 180° - 100
A3 = 80°
Penjelasan dengan langkah-langkah:
k//g
B1 = 100°
A1 = 40°
A2 = B1 – A1
A2 = 100 – 40
A2 = 60°
C2 = 180° – A1
C2 = 180 – 40
C2 = 140°
A3 = 180° – ( A1 + A2)
A3 = 180 – ( 40 + 60)
A3 = 180 – 100
