Answer:
proably and acute angle
Step-by-step explanation:
acute angles are angles that are less than 90 degrees and the picture obviouly shows an angle that is less than 90
![A=\left[\begin{array}{ccc}3&-2\\4&-3\end{array}\right]](https://tex.z-dn.net/?f=A%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%26-2%5C%5C4%26-3%5Cend%7Barray%7D%5Cright%5D)
We can find the A as shown below:
Given A^2=I
We know that A^2=A×A
And ![I=\left[\begin{array}{ccc}1&0\\0&1\end{array}\right]](https://tex.z-dn.net/?f=I%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%5C%5C0%261%5Cend%7Barray%7D%5Cright%5D)
So, ![A^2=\left[\begin{array}{ccc}1&0\\0&1\end{array}\right]](https://tex.z-dn.net/?f=A%5E2%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%5C%5C0%261%5Cend%7Barray%7D%5Cright%5D)
Let
![A^2=\left[\begin{array}{ccc}3&-2\\4&-3\end{array}\right] \left[\begin{array}{ccc}3&-2\\4&-3\end{array}\right]](https://tex.z-dn.net/?f=A%5E2%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%26-2%5C%5C4%26-3%5Cend%7Barray%7D%5Cright%5D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%26-2%5C%5C4%26-3%5Cend%7Barray%7D%5Cright%5D)
![A^2=\left[\begin{array}{ccc}9-8&-6+6\\12-12&-8+9\end{array}\right]](https://tex.z-dn.net/?f=A%5E2%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D9-8%26-6%2B6%5C%5C12-12%26-8%2B9%5Cend%7Barray%7D%5Cright%5D)
Hence,
Hence, option C is correct
