Answer:
The other legs are 9 and 9√3
Step-by-step explanation:
The longer side of a 30-60-90 degree rectangle is 18.
The other legs will be

and

Where x is the longest side, which is given as 18.
Therefore one leg will be:

and the other leg will be:

A(x) = P(1.02)^x
A(x) = P(1 + 0.02)^x
A(x) = P(1 + r)^x
Therefore rate of change = 0.02 = 2%
15 divided by 3 is 5
15 - 3=13
8,800.002816 as one mile equals 1760.0005632 yards
