Approached the "hinderer" cube.
In one study, 6- and 10-month-old infants watched as a red wooden ball repeatedly "attempted" to climb up a hill. Next, the "climber" ball was either "helped" by a pyramid or "hindered" by a cube. Infants at both ages were surprised when the "climber" ball: T/F

uhhh idk u yolo?

i think the answer is d im not sure

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
