Help please I really don’t understand due in 5 days it’s on mathswatch

x>15

Step-by-step explanation:

x/3 +9> 14

x/3>14 -9

x/3>5

x> 5*3

x>15

< 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
