Without writing the equation x^2 + y^2 + 22x – 14y+49 = 0 in the standard form, state whether the graph of this equation is a parabola, circle, ellipse, or hyperbola.
a. parabola
c. circle
b. ellipse
d. hyperbola

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
