Step-by-step explanation:

Because when you draw the Z in the diagram you will see that three and four are outside which means it is corresponding

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

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
