Answer:
In short, 0 is the only number such that for any number x, x + 0 = x.
Step-by-step explanation:

Answer:
The listener is approximately 71.414 feet far from the whisperer.
Step-by-step explanation:
We must remember that two fundamental variables for every ellipse are the major semiaxis (
) and the minor semiaxis (
). The major semiaxis equals a half of the length of the whispering gallery, whereas the minor semiaxis equals a half of the width of the whispering gallery. These are:
and 
The distance between both whisperers (
), measured in feet, is two times the distance between center and any of the foci (
), measured in feet, whose valued is obtained by using this Pythagorean identity:

If
and
, then:




The listener is approximately 71.414 feet far from the whisperer.
