Dani is helping her dad to organise a barbeque. They want an equal number of bread rolls, burgers and cheese slices.
- There are 18 burgers in each packet.
- There are 15 bread rolls in each packet.
- There are 12 cheese slices in each packet.
What is the smallest number of each packet that they can buy?

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

middle maybe?
