FORTY POINTS PLEASE HELP TIMED TEST Elliot is graduating from college in six months, but he will need a loan in the amount of $4,850
for his last semester. He may either receive an unsubsidized Stafford Loan with an interest rate
of 6.8%, compounded monthly, or his parents may get a PLUS Loan with an interest rate of
7.8%, compounded monthly. The Stafford Loan has a grace period of six months from the time
of graduation. Which loan will have a higher balance and by how much at the time of
repayment?

< 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

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
