Part A: McKenzie has a credit card with a balance of . The APR on this credit card is . If she makes payments of , how long will it take her to pay off the credit card? Part B: In the problem above, how much interest will McKenzie have paid when she pays off the credit card?

Part C: How much more interest will McKenzie pay if she only pays per month?

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
