Answer:
No, it is not a right triangle.
Explanation:
We know that there are 2 legs and 1 hypotenuse. The hypotenuse is 76 because it is the largest number. And the two legs are 73 and 26. Now to find if it is a right triangle we will take 73 and multiply it by itself, which is 5,329. Now we will do the same with 26 and we get 676. Then we add 676 to 5,329 and we get 6,005. Because we are trying to find the hypotenuse, we have to find what number when squared makes 6,005. Since 76 x 76 = 5,776 it is not a right triangle.
