You are directed to give a heroin addict 30 mg of methadone po. the medication comes in tablets labeled 20 mg/tablet. how many tablets would you give the patient?

step-by-step explanation:

ddd

< 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
