Final answer:
A triangle with side lengths 19, 23, and 29 yards is not a right triangle.
Step-by-step explanation:
A triangle is a right triangle if and only if the square of the length of the longest side is equal to the sum of the squares of the other two sides. This is known as the Pythagorean theorem. In this case, the longest side of the triangle is 29 yards. So, to determine if it is a right triangle, we need to check if 29^2 is equal to 19^2 + 23^2.
29^2 = 841, 19^2 + 23^2 = 361 + 529 = 890. Since 841 is not equal to 890, the triangle with side lengths 19 yards, 23 yards, and 29 yards is not a right triangle.
