-An experiment was performed to find the average speed of a grasshopper. The average speed has been plotted on the number line as marked by the arrow. -What is the speed of the grasshopper in feet per second?
-Convert the speed to another unit of length per second. Round your answer to the nearest thousandth. Defend your answer mathematically.
-how many minutes would it take this grasshopper to cover a distance of 1,000 feet?show your work
-how much slower in miles per hour, is the grasshopper than a car traveling at 55 miles per hour?show your work

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
