Find the sample size necessary for an 80% confidence level with a maximal margin of error e = 0.12 for the mean weights of the hummingbirds. (round up to the nearest whole number.) 6 correct: your answer is correct. hummingbirds

13cm

step-by-step explanation:

(apex)

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

hm let me think hm think think hm think yes
