What does the blue dot represent?

1

Step-by-step explanation:

The line shows only -7 and -3, so I can figure out that each line represents 2 more than the before number. So if you do -3 + 2 + 2, you will get 1.

think about it deeply and passionately about this property

i am sorry

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
