An archetype appears repeatedly throughout history. Its' a B. Prototype-an original idea that has come to be used over and over again.
Answer:
x = 17 ft ... ( nearest 10th of a foot )
Step-by-step explanation:
Given:-
- The side length of inner square = x ft
- The side length of outer square = 20 ft
Find:-
Find the side length of the inner square that would make the area of the inner square equal to 75% of the total area of the garden.
Solution:-
- Compute the area of the inner square (A_i) using side length (x):
A_i = side length ^2
A_i = x^2 ft^2
- The area of the entire garden is the area (A_o) of the outer square with side length equal to 20 ft.
A_o = side length ^2
A_o = 20^2
A_o = 400 ft^2
- The 75% of the entire garden is :
(75 / 100)*A_o
(75 / 100)*400
300 ft^2
- The area of the inner square is 75% of the entire garden the mathematical expression for it is:
A_i = 300 ft^2
x^2 = 300 ft^2
- The side length required for the inner square is the solution to the quadratic equation above:
x = √300
x = 17.320508ft.
x = 17 ft ... ( nearest 10th of a foot )
ANSWER
B. 12
EXPLANATION
The given triangle is isosceles, because two of the arms are equal.
The angles directly under these two arms and the base are equal.
Therefore the three angles of the isosceles triangle are
84°, 4x°,4x°
The sum of these angles is 180°
Group similar terms,
Divide both sides by 8
The correct choice is B.
