Answer:
x=50
Step-by-step explanation:
since all triangles angles add up to 180 and x and the other corner look equal, than minus 80 from 180 and then divide by two (because of the 2 corners.) x=50 degrees
The correct answer is option C which is ![\left[\begin{array}{cc}8&32\\39&15&\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D8%2632%5C%5C39%2615%26%5C%5C%5Cend%7Barray%7D%5Cright%5D)

<h3>What is a matrix?</h3>
Matrix is defined as the arrangement of the numbers variables and expressions in the table as rows and columns.
The multiplication of the matrix will be calculated as:-
M = ![\dfrac{1}{2}\left[\begin{array}{cc}12&64&\\78&30&\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D12%2664%26%5C%5C78%2630%26%5C%5C%5Cend%7Barray%7D%5Cright%5D)
M = ![\left[\begin{array}{cc}\dfrac{12}{2}&\dfrac{64}{2}&\\\dfrac{78}{2}&\dfrac{30}{2}&\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D%5Cdfrac%7B12%7D%7B2%7D%26%5Cdfrac%7B64%7D%7B2%7D%26%5C%5C%5Cdfrac%7B78%7D%7B2%7D%26%5Cdfrac%7B30%7D%7B2%7D%26%5C%5C%5Cend%7Barray%7D%5Cright%5D)
M = .
Therefore the correct answer is option C which is .

The greatest common factor of 2 and 4 is 2
The square of an odd number:
We're to conjecture, not do algebra, apparently. 1²=1, 3²=9, 5²=25, 7²=49, ...
We conjecture the square of an odd number is odd.
The product of two evens and an odd:
Again, we'll run some examples.
(2)(2)(1)=4
(2)(4)(3)=24
(4)(6)(5) =120
(4)(8)(1)=32
Conjecture: The product of two evens and an odd is a multiple of 4
Counterexample: The product of two fractions is never an integer
How about
3/4 × 4/3 = 1
