Can someone PLEASE help me here I forgot how to do it is due today! I’ll give brainliest !!

Good luck bro

Step-by-step explanation:

10. Variable : x = 4.78

60(x)=287

11. x = 94

$6.90 - $1.25 = $5.65

6(x) = 5.65

Sorry I couldn't do all someone else can do the 2 others

< 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
