Question
Chaidh iarraidh air sgoilearan ann an clas buinn a shadail. B' e an toradh a bh' ann 13 cinn agus 17 earbaill.
Seall am fiosrachadh seo ann an cl脿r-cearcaill.
Bhon a tha 30 toradh ann, roinn 360 le 30, agus mar sin tha 12 ceuman anns gach roinn.
Cinn \(= 13 \times 12 = 156^{\circ}\)
Earbaill \(= 17 \times 12 = 204^{\circ}\)
