Consider in triangle as given below:

sin(A) = opposite/hypotenuse = BC/AC
cos(B) = adjacent/hypotenuse = BC/AC

<span>Now, both of them have the same hypotenuse and both will be equal. As you have seen already both the values are same.
</span>Thus, the <span>relationship between the sine of an angle and cosine of the other acute angle in the same triangle is shown below. And this ill this be true every time.</span>

Stion<br> Factor the difference of squares.<br> x2 - 400<br> The factored form of x2 - 400 is
Sloan [31]

Answer:

The factored form of x²-400 is (x+20)(x-20).

Step-by-step explanation:

Given the expression

x^2\:-\:400

As the square of 20 is 400. Therefore, rewrite 400 as 20²

⇒ x^2-20^2

\mathrm{Apply\:Difference\:of\:Two\:Squares\:Formula:\:}x^2-y^2=\left(x+y\right)\left(x-y\right)

Thus, the expression becomes

x^2-20^2=\left(x+20\right)\left(x-20\right)

Thus, the factored form of x²-400 is (x+20)(x-20).

6200 rupees

Step-by-step explanation:

Think the monthly income x

According to the question

The equation is

x×28%=1736

x×28/100=1736

x=1736÷28/100

x=1736×100/28

x=62×100

x=6200

So monthly income is 6200 rupees

21. You are making a rectangular poster to advertise a school fundraiser. You
liubo4ka [24]

The simplified expression for perimeter is 6w, and for area is 2w². 3 meters of a width will allow the most area while not exceeding a perimeter of 20 meters.

Step-by-step explanation:

Let w represent the width of the poster then,

The length of the poster is twice as long as its width, to mean the length is 2w

Perimeter is the distance around the figure. Your figure is a rectangle with sides width, w and length 2w;

Perimeter formula is = 2(l+w) where l is length and w is with

P=2(2w+w) = 2(3w) = 6w meters

Area is given by the product of length and width of the figure

Area=l*w

A=2w*w= 2w²

The table will be;

<u>Width in (m)       Perimeter=6w in (m)           Area (2w²) in m²</u>

3                          6*3= 18                                   2*3²=2*9=18

4                          6*4=24                                  2*4²=2*16=32

Width 3 allows for the most area while not exceeding a perimeter of 20 meters.
