80° is the measure of gh
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
