The trigonometry illustrates that the four angles whose cosine is the same as cos pi/3 will be 7∏/3, 13∏/3, 19∏/3, and 31∏/3
<h3>How to illustrate the information?</h3>
From the information, given cos (x), the value that is similar to cos x will be the sum of the angle and multiple of 360.
Therefore, for the angle cos(∏/3), the angles that are similar to this angle will be expressed as Cos(2∏n + ∏/3) where n is any positive integer.
Then the other four angles will be 7∏/3, 13∏/3, 19∏/3, and 31∏/3. Also, the statement that all angles that have the same cosine will have the same sine is false. The sine of an angle is simply equal to the cosine of the complementary angle.

Given expression is
<h3>What is a factor?</h3>
A factor is a number that divides another number leaving no remainder
After we split 42x into 21x each,
The expression looks like,
Taking 3x+7 as common
So factors will be (3x+7) and (3x+7).
Therefore,
Factors of the given expression will be .

Answer:
36
Step-by-step explanation:
In this example, s=6
6^2=36
or you can think about it like this:
you have 6 squares across and 6 down, how many do you have totle?
■■■■■■
■■■■■■
■■■■■■
■■■■■■
■■■■■■
■■■■■■
Then count them for a totle of 36
Set up an equation when x is the cost of a book. If we know that 45 + 5 = 50:
45x = 50(x - .1)
Now, multiply across the parentheses:
45x = 50x - 5 (Now, combine terms over the equal sign)
-50x -50x
-5x = -5 (Now, divide off the -5 from both sides)
/-5 /-5
x = 1
This means that the current cost of a book is <em><u>$1.</u></em> This works out if you test it.
Hope this helps!
