The ladder is the hypotenuse of a 45 45 90 triangle.
The legs of a 45 45 90 triangle = hypotenuse / sqroot (2)
15 / 1.414 = 10.608
(Incidentally it is the "bottom" of the ladder that is 10.608 feet from the wall. The "top" of the ladder is touching the wall. LOL)

Hope this helped :)
Whenever you complete a square, you're really taking this:
(x+b)^2=x^2+2bx+b^2 [/tex]
And equating roots. Here, the b is clearly 11 (2b=22 implies b=11), so that means we want 121 as our ending number. That means we should add 121 to both sides to get:

Answer:
<em>Distance from her house to her work = 12.4 Miles</em>
Step-by-step explanation:
Given :-
<em>==> Automator mileage gauge read 38643.8 Miles before she left to work.</em>
<em>==> Automator mileage gauge read 38668.6 Miles after she came home from work.</em>
<em>==> She didn't drive anywhere else during the day. home to work & work to home.</em>
Car driven during the day = 38668.6 - 38643.8
= 24.8 Miles
Let the distance from home to work be X
*It is assumed that Distance from home to work = Distance from work to home
So, Distance from work to home = X
Total distance driven during the day = Distance from home to work + Distance from work to home
Total distance driven during the day = X + X
24.8 = 2X
24.8 ÷ 2 = X
12.4 = X
<u><em>Distance from her house to her work = 12.4 Miles</em></u>
