The line segment between the points (8,-7) and (4,5) is the diameter of the circle. Find the equation of this circle

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

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
