    Answer: no

    Step-by-step explanation:

    because when you Multiply 7 to the power of 2 its automatically greater than the actual answer and obviously the 9 to the power of 2 already is a lot greater than 11 times 11.

    Answer:

    It is not a right triangle because the other side is 11 and not 11.40  when we apply the Pythagoras theorem rule on it

    Step-by-step explanation:

    To determine whether it is a right triangle, all we simply need to do is to check using the Pythagoras theorem formula, Using the Pythagoras theorm formula;

    opposite² + adjacent² = hypotenuse²

    let opposite  = 7 and let adjacent = 9   let the hypotenuse be x, if we calculate and x gives 11 then we will know it is a right-triangle

    7² + 9² = x²

    49 + 81 = x²

    130 = x²

    Take the square root of both-side

    √130 =√ x²

    11.40 = x

    Therefore it is not a right triangle because the other side is 11 and not 11.40  when we apply the Pythagoras theorem rule on it
