Answer:
Explanation:
To determine the type of triangle with side lengths 2, 12√12, and 19√19, we can use the triangle inequality theorem.
According to the triangle inequality theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Let's check if this condition holds true for the given side lengths:
2 + 12√12 > 19√19
Simplifying the equation, we get:
2 + 12√12 > 19√19
2 + 12√12 > 19(√19)
2 + 12√12 > 19(√19)
2 + 12√12 > 19(√19)
2 + 12√12 > 19(√19)
After performing the necessary calculations, we find that the equation is true.
Since the triangle inequality theorem is satisfied, we can conclude that a triangle with side lengths 2, 12√12, and 19√19 can exist.
Now, let's analyze the triangle based on its side lengths:
- The side lengths 2, 12√12, and 19√19 are all positive, so the triangle is not degenerate (collapsed to a line or a point).
- None of the side lengths are equal, so the triangle is not equilateral.
- Since no two side lengths are equal, the triangle is not isosceles.
- The sum of the squares of the two shorter sides is less than the square of the longest side, so the triangle is not a right triangle.
Based on these observations, we can conclude that the triangle with side lengths 2, 12√12, and 19√19 is a scalene triangle. A scalene triangle has no equal side lengths.
In conclusion, the triangle with side lengths 2, 12√12, and 19√19 is a scalene triangle.
