There is an average of 3.5×10−2 kilogramsof dissolved salt in each liter of seawater. the indian ocean contains approximately 2.64×1020 liters of seawater. about how many kilograms of dissolved salt are in the indian ocean? enter your answer, in scientific notation, in the boxes.

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
