By the Pythagorean Theorem, the hypotenuse squared is equal to the sum of the sides squared...
h^2=x^2+y^2
We are told that y=x+20 and h=24 so
x^2+(x+20)^2=24^2
x^2+x^2+40x+400=576
2x^2+40x+400=576
2x^2+40x=176
x^2+20x=88
x^2+20x+100=188
(x+10)^2=188
x+10=±√188
x=-10±√188, x>0 so
x=-10+√188 ft
y=10+√188 ft
If you want approximations...
x≈3.71 ft
y≈23.71 ft

Answer:
The type of sampling used in the given statement is simple random sampling.
<u>Simple random sampling:</u> This is the type of probability sampling. In this type of sampling each and every unit of the population has an equal chance of being included in the sample. There are various of methods of choosing the sample randomly such as lottery method, use of random number tables, use of computers to generate random numbers etc.
In the given example, a pollster uses a computer to generate the random numbers and interviews the voters corresponding to those random numbers. Therefore, the method used here is simple random sampling.
