Answer:

Step-by-step explanation:
Since we are given the hypotenuse which is 18 since it slanted, and leans on the house. And we are given one of the legs which is 15 since it is vertical. We can use the pythagorean theorem to solve for this problem.

where a and b are the legs and c is the hypotenuse l.
Let plug it in






Step-by-step explanation:
hope this helps you dear friend.
The perimeter would be rational due to both the width and length being rational numbers. A rational number is a number that can be written as a fraction such as 8 it can be written as 8/1, but a irrational would be a decimal number which in this case there would be none because both length and width is rational number. For example, Lets say the width is 8 and the length is 10. once both are written into fraction form such as 8/1 and 10/1 we add them to get a perimeter of 18.

Answer:
cannot be determined
Step-by-step explanation:
If <em>x</em> = 0.4333…, then
10<em>x</em> = 4.333…
100<em>x</em> = 43.333…
so that
100<em>x</em> - 10<em>x</em> = 43.333… - 4.333…
90<em>x</em> = 39
<em>x</em> = 39/90 = 13/30
