If a person's eye level is h meters above sea level and he can see d kilometers to the horizon, then d=3.57\sqrt(h.) Suppose the person's eye level is 15.21 meters above sea level. How far can he see to the horizon?

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
