What is the best estimate of 48%of 60

The estimate would be about 30

Step-by-step explanation:

You should know that half (50%) of 60 is 30, even though the real answer would be 28.8

< 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
