The gas tank in zachary's car has a capacity of 60 liters. he adds 23 liters 825 milliliters of gas to the tank, which already has 2,050 milliliters of gas. how much more gas can zachary add to the gas tank?

< 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
