Answer:
Can not be determined (CNBD)
Step-by-step explanation:
In the given triangle ACI,
M is the mid point of CI, So we have
CM= MI
also AM=AM ( reflexive property )
So far we have two pairs of corresponding sides are congruent in ΔCAM and ΔIAM
To prove that ΔCAM≅ΔIAM using SSS (side side side ) congruence theorem
we should have AC =AI , but it is not given,so we can not say that AC=AI
To prove that ΔCAM≅ΔIAM using SAS (side angle side ) congruence theorem
we should have ∠AMC=∠AMI, but it is not given,so we can not say that ∠AMC=∠AMI
We can not determine that ΔCAM is congruent to which triangle
Hence the answer is Can not be determined (CNBD)
The cofactors of each entry in the first row of the matrix exist
![$$Ac_{11 }= -13](https://tex.z-dn.net/?f=%24%24Ac_%7B11%20%7D%3D%20-13)
![Ac_{12} = 44](https://tex.z-dn.net/?f=Ac_%7B12%7D%20%3D%2044)
![Ac_{13} = 27](https://tex.z-dn.net/?f=Ac_%7B13%7D%20%3D%2027)
We have to estimate the cofactors of each entry in the first row of the matrix.
<h3>What is the matrix?</h3>
A set of numbers exists arranged in rows and columns to create a rectangular array. The numbers exist named the elements, or entries, of the matrix.
Thus the cofactors of each entry in the first row of the matrix exist
![$$Ac_{11 }= -13](https://tex.z-dn.net/?f=%24%24Ac_%7B11%20%7D%3D%20-13)
![Ac_{12} = 44](https://tex.z-dn.net/?f=Ac_%7B12%7D%20%3D%2044)
![Ac_{13} = 27](https://tex.z-dn.net/?f=Ac_%7B13%7D%20%3D%2027)
