Besar sudut BAC adalah.....

Kak tolong dijawab beserta caranya ya...​

140° = y + 10° + 2y + 10°

140° = 3y + 20°

3y = 140° - 20°

3y = 120°

y = 120°/3

y = 40°

sudut BAC

= y + 10°

= 40° + 10°

= 50°

opsi c

Penjelasan dengan langkah-langkah:

y + 10 + 2y + 10 = 140

y +2y + 10 + 10 = 140

3y = 140 - 10 - 10

3y = 120

y = 120/3

y = 40°

<BAC

y + 10

40 + 10

50
