Answer:
55 feet
Step-by-step explanation:
If you draw it out, the diagnonal along wiht 2 sides of the rectangle make a rigth angles traingle.
Using pythagoras theoreom, 
, c is the length of the diagonal and a and b are 2 sides of rectangle.
So c=
=
put in alculator and get:
55
=55 feet
Answer:
$3.47
Step-by-step explanation:
$4.88 + d = $8.35

d = $3.47
Answer:
a constant
Step-by-step explanation:
Hi there! :)
4x=-36
Divide both sides by 4 in order to isolate x:
x=-9
Hope this helps you and have a nice day!

If you're trying to find the missing side of the "triangle" (the distance from the house to where the ladder touches the ground), you would use the pythagorean theorem, a²+b²=c². (c is always hypotenuse)
a²+b²=c²
12²+b²=15²
144+b²=225
b²=81
√b²=√81
b=9
