Scenario: Marco collects 12 new coins each year to add to his coin collection. We can represent equivalent ratio relationships with multiple types of models
to show the growth of his coin collection over time.

< 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

1.3

step-by-step explanation:

divide by 9

12/9 =

1.3 =x

the correct answers i think are b. and d.

give me brainliest if it is correct!
