We know that the Circumcenter is the intersection of a triangle's right (perpendicular) bisectors. Once you have found two of these you can determine their point of intersection.

It is a proven mathematical concept that the third perpendicular bisector will also cross through this intersection point. While it is not necessary to construct all three it is often done so to verify that the intersection of the first two perpendicular bisectors was in fact correct.

Answer: 120 ft

<u>Step-by-step explanation:</u>

The Ellipse equation is: $\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1$ where

(h, k) is the center
"a" is the horizontal radius
"b" is the vertical radius
c is the distance from the center to the foci: |a² - b²| = c²

Given: horizontal diameter = 122 → horizontal radius = 61 = a

vertical diameter = 22 → vertical radius = 11 = b

Foci (c): 61² - 11² = c²

3721 - 121 = c²

3600 = c²

±60 = c

Let (h, k) = (0, 0)

Then the foci are located at -60 and +60.

The distance between them is 60 + 60 = 120
