80° segaris dengan (3y-5)° [kalo segaris berarti 180°]180-80 = 100100=3y-53y=-5-1003y=105y=105/3 y=35 x = (x+5)° bertolak belakang dengan 80° jadi angka nya sama80 = x+5x=80-5x=75x-y75-35 = 40°
40°
x + 5° = 80°
x = 80° - 5°
= 75°
(3y - 5)° + 80° = 180°
3y - 75° = 180°
3y = 180° - 75°
= 105°
y = 105°/3
= 35°
x - y = 75° - 35° = 40°

Penjelasan dengan langkah-langkah:
80° segaris dengan (3y-5)° [kalo segaris berarti 180°]
180-80 = 100
100=3y-5
3y=-5-100
3y=105
y=105/3
y=35
x = (x+5)° bertolak belakang dengan 80° jadi angka nya sama
80 = x+5
x=80-5
x=75
x-y
75-35 = 40°
40°
Penjelasan dengan langkah-langkah:
x + 5° = 80°
