Which rule describes the composition of transformations that maps ABC to A"B"C"?
Ro, 900 Orx-axis(x, y)
O
rx-axis º Ro, 900(x, y)
O Ro, 18000 rx-axis(x, y)
Orx-axis 0 Ro 1800(x, y)

the correct answer is d

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
