Answer: No, it is not a right triangle
Explanation:
Let's assume we have a right triangle. If that's the case, then
a^2+b^2 = c^2
would be a true equation where
a = 10 and b = 7 are the two legs of the triangle
c = 12.3 is the hypotenuse (longest side)
Plug the values in and see what happens after we simplify
a^2 + b^2 = c^2
10^2 + 7^2 = (12.3)^2
100 + 49 = 151.29
149 = 151.29
Both sides are not the same number, so this given triangle is not a right triangle.
