Answer:
I think it's 10 because the 30 60 90 triangle rule is x, x sqrt 3, 2x. The 5 matches the x side and the hypotenuse is 2x so 10.
Step-by-step explanation:
Let the width = x feet, then the length = 160 - x feet.
The area = x * (160 - x) = 4000
160x - x^2 = 4000
x^2 - 160x + 4000 = 0
x = [- (-160) +/- sqrt (160^2 - 3 * 1 * 4000)] / 2
x = 128.98 or 31.01
answer is length = 129 feet and width = 31 feet ( to nearest foot).
Answer:
the associative property
Step-by-step explanation:
the associative property allows the numbers to add regardless of how you group the numbers
Triangles a are similar because they have the same degrees
And Triangles d are similar because they are the same shape
