The population of city A is 0.6 million less than the population of city B, and the population of city C is three times that of city B, decreased by 2.7 million. If the sum of the populations of city A, city B and city C is 78.2 million, find the population of each city.

what do u need to know

step-by-step explanation:

c

-by-step explanation:

it would be c

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
