Answer:
>
Step-by-step explanation:
π / 3 is in radians.
Radian need to be converted into
degree ( ° ).
The value of in degree is 180°
π / 3 = 180 / 3 = 60°
60° > 30°
So,
( π / 3 ) > 30°
KL=2*JL
I tried to find the rest of the question online, and I'm not sure if radicals couldn't show up or something, but attached is an image of the rules for a 30-60-90 triangle, so hopefully this helps.
.72 is 72%. Just move the decimal point two places to the right.
Answer:
The number of sleeping bags bought is 17.
Step-by-step explanation:
If we let "x" be the number of the sleeping bags that were bought, we can make the following equation....
(5x)(12) + (x)(45) = 1785
By solving the equation we get....
(5x)(12) + (x)(45) = 1785
60x + 45x = 1785
105x = 1785
x = 1785 / 105
x = 17
There for the number of sleeping bags bough is 17.
A 2 x 2 matrix has 2 rows and 2 columns
A specific 2 x 2 matrix a with no zero entries at all is ![\left[\begin{array}{cc}1&-2\\-3&6&\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D1%26-2%5C%5C-3%266%26%5Cend%7Barray%7D%5Cright%5D)
<h3>How to construct the matrix?</h3>
From the question, we understand that the matrix is a 2 x 2 matrix.
A 2 x 2 matrix is represented as:
![\left[\begin{array}{cc}a&b\\c&d&\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Da%26b%5C%5Cc%26d%26%5Cend%7Barray%7D%5Cright%5D)
Also from the question we understand that the elements of the matrix are non-zero.
This means that:

An example of such matrix is:
![\left[\begin{array}{cc}1&-2\\-3&6&\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D1%26-2%5C%5C-3%266%26%5Cend%7Barray%7D%5Cright%5D)
Note that there are several matrices that fit the given construction requirement
