Addy is doing a science fair project. she wants to find out what type of ball bounces the highest. which one of these will help addy to gather statistical data? A) measuring and recording the height of each ball after it is dropped.

B) dropping the balls at the same time and looking to see which bounced the highest.

step-by-step explanation:

cats

answer: 177/8

step-by-step explanation:

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
