Ellie wants to buy a computer for 900. she cqn save $75 a month on a saving a coount and earn $2 for every $100 she saves. or she can pay back $75 on a bqnk for $900 and pay interest of $7 for every $100 borrowed. how much will ahe pay for the computer for each of her choices

step-by-step explanation:

i am not sure sorry : c

< 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
