Find the midpoint of A and B where A has coordinates (-3,-5) and B has coordinates (4,4).

(, )

Step-by-step explanation:

Use the midpoint formula to solve.

1) Given 2 points: (, ) and (, )

The midpoint formula would be (, ).

2) Based on this, we can easily find the midpoint of AB.

3) With this information, we can solve for the midpoint.  

(, ) --> (, ) --> This is your answer.

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
