Answer:
10 years
Step-by-step explanation:
let they become of same height after t years
3ft=36 inches
hence
height of A
Ha=36+21t
8ft=96 inches
height of B
Hb = 96+15t
as Ha =Hb
36+21t =96+15t
21t-15t =96-36
6t=60
t=60/6
t= 10 years

distance = Sqrt((x2-x1)^2 +(y2-y1)^2)
15-3 =12

12^2 = 144
9^2 = 81
144+81 = 225
square root of 225 = 15
the distance is 15
