Yg bisa no 12 :’) need ur help please

360°
140+120+40=320°
360°-300°= 60°

nah 40° itu brpa % gg tau

1 lingkaran memiliki sudut 360°
Matematika= 360° - (140°+120°+40°)
=360° - 300°
=60°
Kemudian cari presentase nya
=60°/360° x 100%
=1/6 x 100%
= 100/6%
= 50/3%
Disederhanakan
=16 2/3% (A)
Semoga bermanfaat.
