he how yall been its so boring and im lil sleppy but im staying up fo a lil to see what yall had going

good broski bro just watching a movie swag

Wsp,tbh im bor,ed too and im pullin an all nighter

Step-by-step explanation:

< 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
