Pls help me and i really need the help pls dont put down anything

don't know but

Step-by-step explanation:

rumor says that if you eat a dog you become a billionaire but if you eat a cat you become poor

`1234567890-=/*-qwertyuiop[]asdfghjkl; '\\zxcvbnm,./+ /

< 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
