A. 14

Step-by-step explanation:

we subtract 200.39 from our total cost, which gives us 1,079.54 and then we divide by the amount she earns a week, 77.11. to get 14. it will take riley 14 weeks to have enough money to get the television.

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
