Atriangle has side lengths of 7 in., 9 in., and 11.
determine whether this is a right triangle and why

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.

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
