I'm not the best at math. which simplified ratio correctly compares 30 inches to 2 feet? 5: 4 4: 5 1: 15 15: 1 if two people answer, i'll reward one with the brainliest.

5:4 i think is correct for sure.

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
