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

x = 3

step-by-step explanation:

you haven't given us any choices but we can guess.

-35x = - 105       divide by - 35

-35x/-35 = -105/-35   the minus signs cancel out and 105 can be divided evenly by 35

x = 3
