Let the length of the guy wire be x feet.
cos 51.8 = 400/x
x = 400/cos 51.8 = 646.82 feet.
The answer is 646.82 feet.
The shape has 7 sides.
The sum of the interior angles is (7-2)180 = 5 * 180 = 900 degrees.
Divide the total sum by 7:
X = 900 /7 = 128.6 degrees.
For the answer to the question above,
The slope of the line of the line is calculated through the equation,
m = (y2 - y1) / (x2 - x1)
Using the first two points in the given,
m = (-7 - 9) / (-12 - 8) = 4/5
The line parallel to this has also a slope of 4/5. Through the point-slope form, the equation of the second line is,
y - -15 = (4/5)(x - -5)
Simplifying gives the answer of,
y = (4/5)x -11
Eliminating the fraction,
5y = 4x - 55
I hope my answer helped you.
I wrote down the answer cuz it’s just easier to read that way:)
Answer:
C. 60%
Step-by-step explanation:
<u>Consider 1st row of table</u>
Total Price = P= 22.50
Discount=D=13.50
Percent discount=(D/P) x 100
=(13.5/22.5) x 100
= 60%
<u>Consider 2nd row of table</u>
Total Price = P= 27
Discount=D=16.20
Percent discount=(D/P) x 100
=(16.2/27) x 100
= 60%
Now we know discount rate is r=60%
