In a table do you have to list the x and y coordinates in order (largest to smallest)?

No. (maybe)

Step-by-step explanation:

For expressing the corresponding values of x and y, any ordering will do. It is usually convenient for the user of the table if there is some recognizable order (so that a value can be found without searching the entire table). The usual expected order is by x-value, smallest to largest.

Some problem statements may specify that the table entries be listed in order. In those cases, yes, the table values must be listed as specified. (This accounts for the (maybe) answer, above.)

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
