a. 22.57%
b. 45.14
c. 48.06%
d. 54.86%

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

i dont understand the question? ?

step-by-step explanation:

i dont know

step-by-step explanation:

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
