9 is a parallelogram because parallelograms have parallel sides. and for 10 set 7x+3=3x+35 because its a rectangle and the side lengths are equal. solve to get
4x=32
x=8
x=x, so plug in 8for x for bc=2x+5
16+5=21
then plug in x to both equations just in case (ab and dc)
i got 59 and 59)
so 59 and 21 are the side lengths, so now use that calculator for the Pythagorean theorem.62.63 about.cuz its a right triangle.
Answer:
Length is twice the Width
Perimeter = 126 ft.
let width = W
length = 2W
P = 2 length + 2 width
126 ft. = 2(2W) + 2W
126 ft. = 6W
21 ft. = W
width is 21ft., length is 42 ft.

Cosine is a trigonometric function. The value of cos(x+π), when the value of cos(x)=-(√3)/2 is √3/2. The correct option is A.
<h3>What is a cosine?</h3>
Cosine is the trigonometric function equal to the ratio of the side next to an acute angle to the hypotenuse in a right-angled triangle.
Given the value of cos(x)=-(√3)/2, therefore, the value of x can be written as,
cos(x) = -(√3)/2
(x) = cos⁻¹ [-(√3)/2]
x = 5π/6 = 150°
Now, the value of cos(x+π) will be,
cos(x+π)
= cos[(5π/6)+π]
= cos(11π/6)
= √3 / 2
Hence, the value of cos(x+π), when the value of cos(x)=-(√3)/2 is √3/2.
