The answer isw c because when i first looked at it i was like its a then i soveled the problem out
Step-by-step explanation:
I used a co-ordinate graph and place the ticket booth at the origin then I chose difference of four but you can choose any and place three events equidistant from the origin by using the X- and Y- axis to easily determined a distance of 4 from the origin .
(0-4, 0) =( 4,0)
(0+4, 0) = (4 ,0)
(0, 0+4) = (0, 4)
if the both are placed first u would need to find the equation of a circle that contains all three points and place the booth at centre
you do this by creating the system of 3 equations inputting the x,y coordinates of each booth and solving for h,k,r
equation of a circle (X-H) 2 +( Y-K) 2 = r2
Hope It helps
:DD have a nice day
