Does the shape have rotational symmetry? if so, what is the angle of rotation, rounded to the nearest degree? a. no, 0° b. yes, 45° c. yes, 72° d. yes, 60°

Sure. That looks like if we rotated it one fifth of a circle it would be the same, similar to a pentagon.

360/5=72

72 degrees, C

555.99.

step-by-step explanation:

hope this

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
