The average annual salary of the employees of a company in the year 2005 was $70,000. it increased by the same factor each year and in 2006, the average annual salary was $82,000. let f(x) represent the average annual salary, in thousand dollars, after x years since 2005.

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
