9.42
Step-by-step explanation:
We know that and this is the only point when sin and cos are equal lengths. Because both
Now if the sin of 30° is a half that would mean that cos of 60° is also a half.
Hope this helps.

Answer:
The width of the similar rug is 3 ft
Step-by-step explanation:
Calculate the percentage between the lengths:
3/9 = 1/3 (percentage)
The percentage is fixed for the widths as well which means 1/x = 1/3
x=3
To correctly solve x from the given equation,
3x - 3 = 6x + 1
We first subtract 3x from both sides of the equation and this will give us,
-3 = (6x - 3x) + 1
Simplifying,
-3 = 3x + 1
Then, subtract 1 again from both sides of the equation to give,
-4 = 3x
Lastly, divide both sides by 3 giving us a final answer for x which is x = -4/3.
