Answer:
Yes, it will fit snugly in a 90º corner
Step-by-step explanation:
To do this, we simply need to check if the given sides of the shelf is right-angled.
So, we have:
![Hypotenuse = \sqrt{242](https://tex.z-dn.net/?f=Hypotenuse%20%3D%20%5Csqrt%7B242)
![Side\ 1 = Side\ 2 = 11](https://tex.z-dn.net/?f=Side%5C%201%20%3D%20Side%5C%202%20%3D%2011)
To check for right-angle triangle, we make use of:
![Side\ 1^2 + Side\ 2^2 = Hypotenuse^2](https://tex.z-dn.net/?f=Side%5C%201%5E2%20%2B%20Side%5C%202%5E2%20%3D%20Hypotenuse%5E2)
This gives:
![11^2 + 11^2 = \sqrt{242}^2](https://tex.z-dn.net/?f=11%5E2%20%2B%2011%5E2%20%3D%20%5Csqrt%7B242%7D%5E2)
![121 + 121 = \sqrt{242}^2](https://tex.z-dn.net/?f=121%20%2B%20121%20%3D%20%5Csqrt%7B242%7D%5E2)
![242 = \sqrt{242}^2](https://tex.z-dn.net/?f=242%20%3D%20%5Csqrt%7B242%7D%5E2)
![242 = 242](https://tex.z-dn.net/?f=242%20%3D%20242)
This shows that the given sides of the shelf is a right-angled triangle.
Hence, it will fit the wall
This answer is c (x-4)(x+4)
