Which conditional has the same truth value as its converse? a. if x = 7, then |x| = 7. b. if a figure is a square, then it has four sides. c. if x – 17 = 4, then x = 21. d. if an angle has a measure of 80°, then it is acute.

whats the

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
