Alake near the arctic circle is covered by sheet of ice during the cold winter months. when spring arrives, the ice starts to melt. s models the ice sheet's thickness (in meters) after t weeks. s=-0.25t+4 what is the ice sheet's thickness at the beginning of spring?

answer: -0.5 would be the most likley outcome

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
