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
