A company is planning to set up a new manufacturing plant for giant inflatable beach balls and believe the costs follow a linear model. The cost analysts estimate the cost of producing 10,000 beach balls to be $587,500 and the cost of producing 50,000 beach balls to be $717,500

step-by-step explanation:

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
