In an experiment, a petri dish with a colony of bacteria is exposed to cold temperatures
and then warmed again. use the model to estimate the population of bacteria at 9 hours. (model is below)

time (hours): 0 1 2 3 4 5 6
population (1000s): 5.1, 3.03, 1.72, 1.17, 1.38, 2.35, 4.08

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
