Which set of ordered pairs (x, y) could represent a linear function? A = {(-9,4), (-4,1), (2,-2), (7,-5)}
B = {(-1,9), (5,7), (7,6), (9,5)}
C = {(-3, -3), (0, -1), (2, 1), (4,3)}
D = {(-5,5), (-1,4), (3,3), (7,2)}

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

your answer is c. 97 (don't delete this again)
