Is the triangle with the given dimensions a right triangle? If so, which angle is the right angle?

Answer:
D. No, it is not a right triangle.
Step-by-step explanation:
Because of following reason:
[tex] {10}^{2} = 100...(1) \\ {8}^{2} + {5}^{2} = 64 + 25 = 89...(2) \\ from \: (1) \: and \: (2) \: it \: is \: obvious \: that : \\ {10}^{2} \neq{8}^{2} + {5}^{2} \\ [/tex]
Hence, it is not a right triangle.
