    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.

    No it would not.

    Because the sum of the squares of the two short sides is not equal to the square of the largest side.

    7^2 + 10^2 = / = 12.3^2
