Can the sides of a triangle have lengths 3, 15, and 15

Answer 1

No, the sides of a triangle cannot have lengths 3, 15, and 15. 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 remaining side. However, in this case, 3 + 15 is not greater than 15, so these side lengths cannot form a valid triangle.
