Prove that the geodesic on a circular cylinder is a helix. [Hints: Roll a piece of lined paper into a cylinder to see the helical curves. Notice that rolling up the paper does not change the geodesic property of the curves on the surface, Why not

step-by-step explanation:

the answer is y = 11.54

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

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
